Hi!
Hi all,
can one please have a lokk at this? aplay -N isn't working for the OP.
TI> Cannot reproduce here. Could you _post_ more details?
OK, I've tested more, and discovered that the problem seems to be that the end of the sound is cut in non-blocking mode. And if I play a very short sound-file, I can't hear anything. Blocking mode works fine.
When using non-blocking mode, an strace contains "ioctl(4, 0x4144, 0x2b9f785d8000) = -1 EAGAIN (Resource temporarily unavailable)". Blocking mode never contains the EAGAIN response.
I attach two files. When playing halt.au, I can only hear the start, about as much as "ha". When playing metal.au, I can't hear anything.
System info:
ASUS A8V Deluxe motherboard with Athlon 64 3500+ CPU VIA 8237 with ALC850 sound Linux 2.6.22.2 kernel for amd64 Debian testing amd64 with: alsa-utils 1.0.14-1 libasound2 1.0.14a-2 libc6 2.6.1-1
I hope this helps. Please ask if you need more info.

Thanks for the suggestion.
Unfortunately, it didn't solve my problem, no sound when non-blocking mode is used. New strace:

I have no idea, so forwarded to alsa-dev then.
