My android system has s/pdif optical out.
I can't control volume when I using optical cable.
In my laptop's Linux, S/PDIF volume is controlled by ALSA and android's kernel configuration is also include alsa.(But cannot control)
Is there any method to control volume?
I have source code and kernel configuration.(So, I can build it)
Thank you very much.
I found that, not only alsa but also pulseaudio is needed for volume control of spdif digital out on linux.
Only alsa cannot control volume of spdif.

I have a question about default_gain.conf. I have found many threads on how to boost volume to the headset using default_gain but from my testing this only effects music volume like pandora. My incall volume is still very low. Does anyone know the values I need to modify to adjust just the incall volume through the headset port?
There is a feature called sound control in custom kernels, i would like to know what this is
Its an option to increase or decrease volume of headphone or phone speaker more than default volume set use faux sound or trickster mod app
I have been researching and playing around with mixer_paths.xml file in an effort to increase the volume of my phone as well as the gain of the mic.
I would like to share what I have found and open it up to the community.
Location
Code:
/system/etc/mixer_paths.xml
Purpose
The mixer_paths file acts as a audio routing map of sorts. It controls the routing of audio to the various registers on the DAC (Digital-to-Analog Converter). It assigns the registers as well as digital volume levels, digital gain, and analog gain.
Additional Info/References
The Nexus 5 is equipped with the WCD9320 DAC.
Codec source code
Sound Control (faux/flar2)
I am keeping my work and notes here on Github.
Comparing Flar2's implementation of Sound Control (which is based on Faux's Sound Control) it appears that we can accomplish the same volume and gain modifications using mixer_paths.
Does anyone have the datasheet for the WCD9320 DAC?
Volume control of Blueooth is HELL on my Sony Z5 Compact.
step 2 is too low and step 3 is too loud (ARGHGHGH)
So i was thinking that maybe i could simply disable volume control and control them seperately ?
eg set the phone to eg 50% and then use the volume control on the speaker (Harman Kardon Onyx Studio 3)
if i plug in the phone using Minijack i can do this - but then its not wireless anymore.
what do to ?
any other solutions to the volume bug ?
PS. Ive tried installing a fine-tune volume app and its kind of messed up - works almost but then it doesn't after all ...

You can override this without doing anything special in the Developer's Options
Ohhhh, the "disable absolute volume" option!
I will try it.
Thanks!!
Wondering if I could get some help on this. When I used my old Nexus 7 tablet with my bluetooth headphones which have volume control, when I adjusted the volume on the headphones using the physical buttons, it adjusted the system volume in the tablet. However on my Mediapad when I adjust the volume on the same set of headphones, it adjusts the volume independently on the tablet. Basically right now I have two volume controls, one on the tablet, and one on the headphones, and they aren't linked. Any idea how to link them up, so I control the system volume with my headphones?
