Hi !
Thanks for answering me. Yes, turning the output volume up or down as soon as it's playing at full output : it plays at the % it should play.
I'm OK to try the patch, but I don't find the /rme96.c/ file. Where is it located ? I think a recompilation's needed then ? Never done that.
Well, you need to learn how to compile the kernel. It's possible to compile only a module from the current running tree, too.
Which distro are you using? You can ask distro guys for assistance.

Thanks for help.

Hi all !
I don't know if the bug is known from your team, but some people advice me to send an email to the Alsa devel list if nobody answer in the kernel's bugtracking.
Here is the bug I have : https://bugzilla.kernel.org/show_bug.cgi?id=105771
What do you think about it ?
Does the volume go down when you adjust DAC volume by mixer application when this happens?
Through a quick glance at the driver code, the only smelling part is that it's calling snd_rme96_reset_dac() from snd_rme96_playback_setrate(). If the DAC volume adjustment really works, the patch below might work. Please give it a try.
The patch has a code to give some delay that is commented out for now. The delay is found in the resume path, but I'm not sure whether it's mandatory. So let's try at first without the delay. If it's unstable, you can uncomment the line and retry.
thanks,
Takashi
