Hello. Information for those who whish to use pulseaudio with sunray audio device: to stop pulseaudio crashes, apply the following patch to sunray audio kernel module, and recompile --- utadem.c.orig 2007-08-17 17:25:37.000000000 +0400 +++ utadem.c 2007-10-09 12:42:30.000000000 +0400 @@ -971,6 +971,7 @@ else if (size < (seqlen_sec / 20)) size = seqlen_sec * 3 / 100; + size &= (~3); return size; } Without this patch, ioctl(SNDCTL_DSP_GETOSPACE) may return size that is not multiply of audio sample size, and single write() operation on dsp device may accept data size that is not multiply of audio sample size. That confuses pulseaudio oss module badly. It would be nice if sun people will include this (or other) fix to the problem into future releases of SRS software. Nikita
