Examining the process using strace reveals, that the file descriptor of the sound device is no longer listed in the readset or writeset when the select() syscall returns. Audio Playback using XMMS is working fine using the OSS API Also the native OSS driver is working fine with both VoIP phones on the same system and kernel. ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- related to 0001300 modprobe goes into D-state when inserti... ====================================================================== ---------------------------------------------------------------------- rlrevell - 10-31-05 17:44 ---------------------------------------------------------------------- Is this problem still present in the latest ALSA release? ---------------------------------------------------------------------- tek01 - 11-07-05 13:00 ---------------------------------------------------------------------- Sorry for the long delay. I've been very busy during the last few month. I did some tests further with Linux 2.6.14 vanilla with preemtion either enabled or disabled using the in kernel ALSA, ALSA 1.0.10rc2 and ALSA CVS from last friday. The problem is still the same as described in my first report independent from preemtion and ALSA version used.
