module-oss get's killed unexpectedly

[linuxrulez.giedrius]

Hello,

Pulseaudio daemon kills module-oss unexpectedly, though module is loaded on command line. There's also a problem with ALSA plugin, but I guest that's the problem with ALSA itself ( sndrv_pcm_hw_params: Assertion `err >= 0' )

You seem to have trouble with your audio device, since write() on the device return "Bad address". What kind of audio device is this? Does dmesg say anything?

[linuxrulez.giedrius]

This is SunRay?2 utadem module. No, dmesg is quiet. This only happens sometimes after stopping audio, but quiet frequently.

[lennart]

Apparently there are some issues with the SunRay? OSS emulation, as mentioned on the ML recently. Since I lack access to any of these machines and SunRay? is closed source software I fear I am unable to help on this.

Sorry,

Lennart

[linuxrulez.giedrius]

I use SRSS 3.1.1 (SUN provides this for free). utadem (audio emulation) module is under GPL:

Replying to lennart:

This is known borkage in the SunRay? OSS driver.
