Hi,
This is my first post here and guess what I am looking for support :)
Up to now I used audioinjector and hifiberry on RaspberryPi and that worked without issues (from alsa point of view).
Now I would like to select vc4hdmi on alsamixer but that complains for missing controls. I think vc4hdmi does not support hard volume setting - like some other devices.
So I read here and there and found softvol. To test I modified vc4-hdmi.conf shipped with alsal-iib from:
# default with dmix vc4-hdmi.pcm.default { @args [ CARD ] @args.CARD { type string } type asym playback.pcm { type plug slave.pcm { @func concat strings [ "dmix:" $CARD ] } } }
to (stolen from PC-Speaker.conf)
# default with dmix vc4-hdmi.pcm.default { @args [ CARD ] @args.CARD { type string } type asym playback.pcm { type plug slave.pcm { type softvol control { name "Master Playback Volume" card $CARD } slave.pcm { @func concat strings [ "dmix:" $CARD ] } } } }
after reboot nothing changes! I build my images with Openembedded/Yocto and from my experience it is possible that there is some misconfiguration / path issue causes problems. I know the card works with the help of pulseaudio.
So now my questions: * Would you expect that my modification of vc4-hdmi.conf adds softvol control to vc4hdmi? * If yes: The only information I have currently: It does not work as expected. So where can I ask alsa for some feedback what went wrong (log-files/dmesg/journal...)?
Thanks in advance
