pulseaudio over network

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I've been building an openwrt router (TL-WR1043ND) to connect my laptop 
to my stereo. The router uses USB audio running pulseausio 1.1.
When I play a song using "paplay -s 192.168.0.44 debaser.wav" it plays 
fine without stuttering. Also "PULSE_SERVER=192.168.0.44 paplay  
debaser.wav" works.
But if I set the default sink to use the pulseaudio on the router it 
stutters. What is the difference beteen the different methods? Seems it 
should be possible using the default sink with the right configuration 
but I can't seem to find how.

On the client:
 >>> jeroen at shuttle:~$ pacmd list-sinks
