I've problem with compiling rme96.c (see attachment). Maybe I forgot something, i double checked, but my rme96.c seems to be good.
Any clue ?
You must have patched wrongly. You reverted the former patches, right?

Hi !
Well done ! It plays without max loud volume, and no errors on output. I tried with the following test :
`aplay -fcd -d3 /dev/zero ;aplay -r96000 -c2 -d3 /dev/zero ;speaker-test -c2 -twav`And it's OK. Then I tried with mplayer and some flac files (44.1 / 48 and 96 KHz sample) : no problem.
I think you found the solution. If there are some future problem this patch generates, I'll only see when using "it" each day. Then, for now, you can commit it ;)
Good to hear. Could you try the revised patch below instead? It does restore DAC volume at the end, after the spinlock, so that we can avoid the ugly delay.
thanks,
Takashi
