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.
