Glad to hear. Did you have to use XXX_SYSTEM_TIMER or any
workaround needed? Or, did it work as is?
but speakers-test produces crackling sine and
fails on test...
Do you mean it aborts some time later after starting the stream?
Could you show the kernel messages? The default debug level
should suffice, I guess. If any, try debug=2.

Hmm, then there is no serious error here. Did you build the driver
with --with-debug=full or --with-debug=detect option?
No, im just building kernel from git with your tree.
Also, run with debug=2. Then it prints the timer/IRQ handling, too.
Does this happen with aplay, too?
Also, please track via strace to check which syscall it gets an error.
Ill try it later, sorry...
Two more things:
-speakers-test on 48khz doesnt produce above errors, but frequency
is still not right
OK, lets postpone this issue.
-24-bit samples is silent for me too
Too? What are other cases that cause silent output?
I saw that "The Source <thesourcehim@xxxxxxxxx " was trying to play
only 24-bit 96khz samples and they were silent.
Also, can you check whether "aplay -M foo.wav" (with 96khz sound file)
gives any output?
How about the patch below for 48kHz?
Didnt changed anything...
OK. Just to make clear: you get any (more or less) reasonable sound,
not silent, with 96kHz stereo, right?
Yes, on 96khz 16bit stereo only
If yes, then there seems a difference between machines or
environments. Could you clarify your system again?
