ICE1724 headphones channel volume control under pulseaudio
Hello,
I have switched to pulseaudio from pure ALSA. And seems I can't find a solution to one thing.
I use M-Audio Revolution 5.1 audio card http://www.seehuhn.de/pages/revolution
It has additional headphones output. So, I have speakers connected to front output and headphones connected to the dedicated separate output.
Headphones volume control is visible in alsamixer:
!!Amixer output

!!-------Mixer controls for card 0 [Revolution51]
Card hw:0 'Revolution51'/'M Audio Revolution-5.1 at 0xb080, irq 20'
Mixer name : 'ICE1724 - multitrack'
Components : ''
Controls : 32
Simple ctrls : 25
Simple mixer control 'PCM',0 <<<< front speakers control
Capabilities: pvolume cvolume cswitch cswitch-joined
Playback channels: Front Left - Front Right
Capture channels: Front Left - Front Right
Limits: Playback 0 - 127 Capture 0 - 152
Front Left: Playback 82 [65%] [-22.50dB] Capture 0 [0%] [-99999.99dB] [off]
Front Right: Playback 82 [65%] [-22.50dB] Capture 0 [0%] [-99999.99dB] [off]
Simple mixer control 'PCM Center',0
Capabilities: pvolume pvolume-joined
Playback channels: Mono
Limits: Playback 0 - 127
Mono: Playback 0 [0%] [-99999.99dB]
Simple mixer control 'PCM Headphone',0 <<<< headphones control
Capabilities: volume
Playback channels: Front Left - Front Right
Capture channels: Front Left - Front Right
Limits: 0 - 127
Front Left: 0 [0%] [-99999.99dB]
Front Right: 0 [0%] [-99999.99dB]
<SNIP>It works all right.
But, how to make pulseaudio aware of this volume control?
Basically, I want to change it through any mixer app (plasma-pa, pavucontrol etc).

Re: ICE1724 headphones channel volume control under pulseaudio
Pulse will likely have a port or profile that you can switch to in e.g. pavucontrol. What's the output of

active port: <analog-output>I tried switching profiles. With 4.0, 4.1 and higher headphone output is still not controllable through pulse. Volume remains as it was set in alsamixer (at 0).
I think default profiles just don't utilize it as it's not something common.
