Whenever I increase the volume in any application sometimes the audio skips and/or repeats until the volume reaches the new percentage. Interfaces related to volume end up ignoring input until the new volume is reached. Any video playing at the time will also pause until the new volume is reached. It's intermittent. There doesn't seem to be a way for me to reliably reproduce it. Output from pulseaudio -vvvv is here : https://gist.github.com/Yomi0/91e3fc04d9744a790020 Is there any more information I need to provide?

you have to provide pulseaudio log with log time by uncomment log time in deamon.conf
Took a bit, but I got it. https://gist.github.com/Yomi0/7c3158577999fd2447cf Anything else?

I'm a little confused. Is there a command you need to me execute to provide more information?
I got this from the alsa-info.sh script... https://gist.github.com/Yomi0/e581ca6d513fd0f532f7
http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/conf/cards/HDA-Intel.conf;hb=HEAD do it help if you remove softvol plugin from front device ? may need reboot and check whether the softvol volume control is really removed -Intel.pcm.front.0 { @args [ CARD ] @args.CARD { type string } type asym playback.pcm { - type softvol - slave.pcm { - type hw - card $CARD - subdevice 0 - } - control { - name "PCM Playback Volume" - card $CARD - } + type hw + card $CARD } capture.pcm { type hw card $CARD } }
That seems to work, but then if I open pavucontrol, HDMI won't appear as an audio output.
(In reply to Yomi from comment #12) > That seems to work, but then if I open pavucontrol, HDMI won't appear as an > audio output. It also seems to mess around with the volume of outputs.
