Hi
I found that hardware volume control for PCM2704 not working.
After plugging this DAC master volume is set to 69%.
I can change it by command line but not by "knob" (setting hardware volume control).

[root@runeaudio etc]# amixer -c DAC scontents
Simple mixer control 'PCM',0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right
Limits: Playback 0 - 64
Mono:
Front Left: Playback 44 [69%] [-20.00dB] [on]
Front Right: Playback 44 [69%] [-20.00dB] [on]
setting by:
[root@runeaudio etc]# amixer -c DAC -q sset PCM 100%
i can get:
[root@runeaudio etc]# amixer -c DAC -R
Simple mixer control 'PCM',0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right
Limits: Playback 0 - 64
Mono:
Front Left: Playback 64 [100%] [0.00dB] [on]
Front Right: Playback 64 [100%] [0.00dB] [on]
so i think the little change in UI is needed to make it working
btw. thanks for great stuff
