/So the patch prevents the wrong max value reset but it's still
incomplete for the left channel volume?/
-> Yes, worst : it plays nothing on left channel -no loud at all ;)
OK.
Just tried with the line 'usleep(range)' uncommented. It's better, no
loud bug (just a big POP sound on speakers on first time, nothing
after), but I have errors in output. I manage to get them with `dmesg`.
See attachment.
No error nor bug when playing two times the same sample frequency, as
expected... Playing alternatively r48000 and r96000 will output errors
each time, despite of no bug, no loud sound, just expected play. Better
then.
That seems not very 'clean'. What do you think about it ?

Hi Takashi !
Sorry for the late answer. I do compile the 'test' kernel after editing
the file with the three lines as you said on your previous mail.
The result is that the bug isn't occurring anymore, tested with 96KHz
sample :
`aplay -fcd -d3 /dev/zero ; aplay -fS32_LE -r96000 -c2 -d3 /dev/zero ;
speaker-test -c2 -twav`
_BUT_, I only have the right speaker that works, I need to change the
volume to restore sound on the left channel.
So the patch prevents the wrong max value reset but it's still
incomplete for the left channel volume?
Did you try to enable the usleep_range() that was commented out in the
patch?

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.
Takashi
Thanks for help.
Kind regards.

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
