Did you build the driver with --with-debug=full or --with-debug=detect option? 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. > Two more things: > -speakers-test on 48khz doesn't produce above errors, but frequency is > still not right OK, let's postpone this issue. > -24-bit samples is silent for me too Too? What are other cases that cause silent output? Also, can you check whether "aplay -M foo.wav" (with 96khz sound file) gives any output? > > How about the patch below for 48kHz? > Didn't changed anything... OK. Just to make clear: you get any (more or less) reasonable sound, not silent, with 96kHz stereo, right? If yes, then there seems a difference between machines or environments. Could you clarify your system again?
