[Q]-Adjusting sound of HDMI out - Acer Iconia A500

Hi folks. For the Iconia 500, is there a way to adjust the volumes of HDMI audio out? When I plug it into my TV, it plays as max volume or it can be muted. I noticed there is no in between. I'd like to adjust the volume out on the tablet itself rather than the TV. Is this possible? The volume I played with, including in-app volumes, seemed to do nothing.

As far as I know, HDMI send digital audio to your TV. It is like sending audio data to your TV instead of signal for analog. When you TV receive the data, it will decode it to signal to the speaker. It is your TV's task to decide the volume to speaker when it send signal to it.
So same to the blu-ray player and set-top-box using HDMI, you only can control volume on your TV.
Please correct me if I'm wrong.

That's what I was afraid of. Oh well. There's non lazy ways of living with it but I was curious if anything could control the actual output itself from the Iconia prior to the TV coming into play.

roku-like audiocast to phone / headphones

Hey all.
I found a rather dirty hack that seems to work better than Bluetooth audio for listening to private audio from the firetv.
Installing bubbleupnp works good on my phone for audio casting to xbmc, so I tried the same on the firetv in reverse.
I had the xposed installer already on the firetv for llama support, so all I needed was to install the bubbleupnp app and bubbleupnp module in xposed.
Experimenting, I played from xbmc to my bubbleupnp app on my phone and it worked. There was a little delay, but it was more constant than the delay that BT headphones have with the firetv. Adjusting the delay on the xbmc app, and I had my private audio. I hadn't tried with any of the other video apps on the firetv, but I'm thinking the delay will be there. At least I can use it for xbmc.
Just wanted to put that out there. Hopefully a better option for sending and listening to audio will come out soon.

so with what you did is, you basically had the audio stream of a video playing on your phone? I have already installed bubbleupnp on both my note 3 and the fire tv (xposed module on both devices too)but im clueless as to how to make this work. all i have managed is to cast audio(but only music and not video) from my phone to the fire tv, or initiate a video from the fire tv to start playing on my phone, making the fire tv a large remote and my phone the video player lol.
thing is I've never used bubbleupnp before so this whole casting thing is new to me. Maybe you are able to give more details as to what you did? what you set the renderer and library to on both your phone and the tv? Would gladly appreciate it as this is the last piece of the puzzle for me as to configuring the fire tv. would really like xbmc to play the video while my phone plays the audio!! thx!!
Exactly as you said it.
Set bubbleupnp to audiocast to my phone.
Listen on my phone.
Get frustrated because bubbleupnp won't ever change their design to be able to sync. Apparently, the delay is inevitable. Not sure why, as allshare seems to have it figured out.
I'm going to give up on this, as I've had no luck from this method. Will wait to see if a BT ad2p(?) Receiver Profile can be used with phones.

You know what im doing now? I play the movie using xbmc, but also start the movie playback on my phone using mx player.But mx player has the capability to only play the audio with the screen off, so thats what im doing now. Its easy enough to get the audio synced, and the batt drain isnt too bad, 16% for 130 minutes movie (DTS downmixing). a 40 minutes itunes web dl would consume about 4% if its on AC3, but i presume it would be very similar even if it was just AAC.
Until a more seamless method comes out, this is what im gonna be doing, as its easy enough, and no extra purchase required

Lol...
I've played around like that in the past. It does put more load on your network and hard drives though. Tolerable but unfortunate.
I'm giving BT another try. Picked up a car mp3 3.5mm out unit from amazon for $8.50 or so that I'll be able to sync up easily enough. i can plug my own headphones up and plug it into the USB chargers at my bed. I'll see how that works. Hopefully this will be an option.
How nice would it have been if they just gave the headphone out thru remote capability like the roku 3....sigh
Do update on how well your new plan goes. Thanks!

Any update or progress on development of using bluetooth headphones without sync issues?
When you guys described the worsening audio offset which cannot be corrected because it keeps getting worse over time, how long does it take to see it noticeably worsened?
The reason i am asking is I finally was able to install Settings.apk and paired my bluetooth headphones (Noontec Zoro wireless BT headphones).
When I played a movie in XBMC, I didn't think the audio offset was that bad. Better yet, I didn't notice that it worsened over time. I watched it for over 20 minutes and didn't notice any change. I did a manual offset of .4 sec to compensate and it seemed fine after 20 minutes or so. Will I notice it after more time?
The only thing on my config that might be different than others is that in XBMC 13.1 Gotham stable release, is that I have Hardware acceleration enabled but I unchecked both Mediacodec and libstagefright (it is the only way that I can watch xvid without stutter and doesn't seem to affect mp4 h264 movies). Maybe someone else can try this?
Also, movies I played on Plex shows the same...small lag but somewhat tolerable and it didn't seem to get worse over time, but I only did this for about 5 minutes.

Have had pretty good luck with xbmc 13.2 beta rc1.
Am using this BT adapter but only have a few issues now. This syncs up to the fire TV and the audio stays in sync with xbmc.
As I stated in my review, the channels are reversed. Not a real big deal as I can switch my headphones manually to the other ear. After checking my son's BT headphones too, I'm beginning to think all the Chinese imports have their audio connections backwards.
As I watch the show tonight, I can say that the BT alternative is working pretty good. I've had it set forward about 0.2sec ahead and it was quite tolerable. Seems to be getting better. Maybe next update will fix it.
Anybody else had any better luck?

So where do you plug this into? The USB port of the AFTV? how do you pair it?

Its a simple little BT receiver that allows a 1/8” headphone jack or jumper to plug into your car aux. It has a battery which lasts three or so hours with headphones plugged in.
To sync, turn on the switch and search with your phone, firetv or whatever you have with BT audio. It automatically connects. Simple. Cheap.
I actually use a pair cheapo 2.4ghz headphones I got as a gift. None audio sync issues I had using a bluetooth transmitter. I just plug it into either the headphone port on the bedroom tv or on the av receiver when I watch in the living room when I can't sleep.
these look nice
The JBL WR2.4 looks nice for under $50 at Amazon

My bedroom TV has a headphone port the side and no av receiver. That tv is technically a computer monitor with hdmi and a tuner. So that may explain why it still has a headphone port. However, many larger TV's still have an audio out (line level, red and white RCA) that can be used with wireless headphones. There are also toslink to analog convertors or HDMI audio extractors that you can get for about $25. You could use one to achieve line level audio.
I have been researching TV's since the living room tv is old. My living room TV is ridiculous it is HD but it is a 50" plasma from 2004 and it was built before ASTC HD tuners were put in TV sets. The last owners left it because it was a pita to move, I can't imagine how much it would have cost in 2004.
The headphone I mentioned appears not to be a good choice in the line level audio output scenario.

Then I am not sure how this approach would be different than using bluetooth headphones other than you getting lucky with this particular unit compared to others. It is bascially a bluetooth headphone without the headphones.
It's great that it works for you though.

You're right. They are no different. What I did notice is the audio did not seem too out of sync if at all with the newer version of xbmc.
Of course, it could just be a coincidence with a movie that had it audio set out of sync already...I don't know. I may have been more tolerant of the prep work in order to get it to work, pause the video, adjust delay forward, unpause and verify.
The point for me was that it was easy. The BT receiver could have been a more expensive one or cheaper. I don't think it matters too much right now as the BT audio is just an unintended positive side effect.
Amazon may enable a better fix soon or someone may mod a custom image with support if the bootloader opens. Its possible. Either way, I'm happy with the amazon TV. There a bunch more options and capabilities available on this xbmc box than any of the others I've had.

[PSA] Viper4Android Support Works and is Glorious

So, I wanted to use my headphones with my Fire TV. In order to do so I purchased an HDMI audio splitter, a device that essentially takes an HDMI signal and converts the audio to analog RCA. I then used an adapter to plug in my headphones. However there was a small issue, without a dedicated amp I have no volume control other than the horrible amplification in Kodi.
My solution was to install Viper4Android. Extra loud mode amplifies the line level signal to bring it to a comfortable listening level along with granular EQ control to help bring up the bass.
Note that your Fire TV must be rooted and busy box must be installed, but the 4.0+ version of V4A works on the Fire TV and oh is it glorious. Note, you will need a mouse in order to configure everything.
thx, does V4A also have an DRC (Dynamic Range Compression = Night mode feature?)
Does it work with V4A on FireTV Stick?
thx

? please fire tv stick 2

Wireless USB headphones only getting single channel audio after 3.0 update?

I have been using a pair of Sony Gold wireless USB headphones on my shield for viewing at night when my family is asleep. Was working great until after the update. When I tried them last night I am only getting audio from the left side. I tried changing the USB audio settings in the menu from 5.1 to stereo to HQ stereo and back, nothing works. This is happening in all apps and in the menu. Tested them w/ my PC and PS4 and work fine there. Any ideas?
i generaly use soundabout when i use usb stuff for sound but it is a new android version so i dont know here sorry.
For me it's the other way around, I was using turtle beach USB DAC for toslink connection to my amplifier, and was only getting stereo sound. Now digital sound, DTS, AC3 is working in kodi and other apps. I have it set to 5.1, and volume control is off. Don't think this helps you in any way, but they did change things related to USB audio, thats for sure.
Did you reboot the shield when changing the sound settings? You must reboot for the changes to take effect.

Surround sound headphones on shield?

Been looking for a way to have surround sound headphones, and was originally looking at some Sony's but either too expensive, or only support optical in... so started looking at some of the gaming headsets and wondered if the shield would work with them. I notice that most of these tend to be usb, so wondered if the shield could pass audio from plex to the headset.
I just want to watch movies from Plex and get surround sound through headphones.. simple enough!?
Surround sound headphones are just marketing. What you're actually looking for is an app that supports HRTF.
Did you ever find out about the surround sound headphone? I've bought 3 different 7.1 gaming headsets but I couldnt get the 7.1 to work via PLEX. Each headset had its own software for the laptop which worked that way so I think its a driver/android issue.

Streaming apps not working when digital output is set to passthrough

I have a TLC C725 50" Android TV and a Samsung 5.2.1 soundbar connected via eARC HDMI. Problem is, if digital output is set to Auto, I get a 1 second delay on everything, and the audio delay setting does nothing (and the soundbar has a audio delay setting that only goes higher in numbers, which makes the delay worse).
If I set it to passthrough, the delay is gone. But if I try to stream a video on Netflix, after a few seconds both audio and video start going very slow, like slow motion. Disney Plus refuses to even play any video. Videos start playing but immediately freeze.
So what's going on? Is it a faulty TV set? Is it a bug? Having tried everything, I'm currently at a loss.
I do have a Fire TV 4K that has a audio sync utility, but then I lose Atmos on Netflix.
Thanks for any help.
