[pulseaudio-discuss] Assertion in module-oss

[Stanley Cai]

Hi,

I built PulseAudio 0.9.11 on ubuntu 8.04, without any special
parameters.  As I ran as "pulseaudio -v" and used pacat for testing,
an assertion jumped out. Here is my log:

----begin of log----

----end of log----

when I disabled "module-suspend-on-idle", it worked well at least
"pacat < /dev/urandom".

Is it a new issue? As I am a newbie to pulseaudio, any help is very appreciated.

Thanks,
