Ive changed the configs and now there is a network connection from host1 to host2, but if i set sound playback to "pulseaudio sound server" on host1 pulseaudio on host2 exits with:

I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
Soft CPU time limit exhausted, terminating.
E: cpulimit.c: Received request to terminate due to CPU overload.
W: module-rescue-streams.c: Failed to move sink input 0 "pulseaudio" to auto_null.

this is maybe because i cant play sound on this machine at all, its a ubuntu server installation.
after boot the following sound modules are loaded.

ive checked the files in /etc/pulse against the one on my local ubuntu that has working pulseaudio support. besides the changes that i made to get network support they are identical.
i followed the steps in the pulseaudi wiki, first steps and perfect setup. but nowhere is really mentioned what has to happen so that pulseaudio works with the hardware. how does pulseaudio know about my soundcard?

dont know of this is important
