[pulseaudio-discuss] Problem with module-oss

[Ken Mandelberg]

My overall goal is to run pulseaudio on a Linux Sunray session which has 
an OSS /dev/dsp. This is kind of a complicated situation, so I am trying 
to do the  equivalent first on a laptop that already has pulse working.

On the laptop (Ubuntu 8.04) it works with an alsa sink.

However, I changed my default.pa to instead use

load-module module-oss device="/dev/dsp" sink_name=output source_name=input

I do hear the startup jingle /usr/share/sounds/startup3.wav on login, 
but I don't know if thats coming from pulse or not. I do see a reference 
to it in the "info".

Anything I then try to "paplay" hangs. I know the /dev/dsp is good 
because mplayer can use it directly with "-ao oss". I can also cat au 
files to the /dev/dsp successfully.

Below is what pacmd sees with "info", right after login.

Any suggestions?
