[alsa-devel] Laggy mixer with Xonar DX snd_virtuoso
Hello Alsa team,
I have a Xonar DX with a laggy volume control, you might have guessed already. Sound will interrupt if the volume change is big like from 100% to 50%, it will only skip a bit if the volume change is smaller. The interruptions/silence last more than 5 seconds easily. I can actually see the mixer slider going up and down on its own.
I am seeking for your help and i'm using 1.0.22.1.
Here goes the alsa-info.sh output, some weird things going on in dmesg http://www.alsa-project.org/db/?f=ee911fe73baa60aac51c62ff787ab8b8bd8565e8

Does this also happen with alsamixer?

The only message from the snd-virtuoso driver is at time 7.696764; some are from a USB audio device and most from the onboard HDA device.

Controlling the volume with alsamixer works well, the sound does not break. If i change the volume with the gnome-applet/pulseaudio i can see the sliders in alsamixer getting affected by my changes with some stuttering and the sound does break as described initially.

The onboard actually works well with the pulseaudio volume applet. Sorry if it filled the log with crap, i use it for microphone input.

Volume changes on the Xonar D1/DX need several milliseconds and thus are relatively slow, compared to most on-board sound cards. However, there are other sound cards that behave the same.
It looks as if the gnome-applet saves all mouse moves and tries to execute the volume changes for all intermediate positions even if the mouse has already moved to the final position. Please file a bug with that mixer.
