[pulseaudio-discuss] pulseaudio-discuss Digest, Vol 20, Issue 4

[Max Kempter]

Thank you for answer my questuions, but I have some more:

1. Could you give me some informations about the server hardware requirements for minimal failure rate and for budget implemention?

2. Is it a good a idea to use Audio kernel with RealTime Preemption, if I want a low latency system?

3.How is it possible to adjust the Default Sample Rate/Type of the server? With sinks/sources it is not a problem, but...?  


I found a typing error at FAQ #22:

original raw:      load-module module-rtp-send source=rtp_monitor  ->this do not work

better is:         load-module module-rtp-send source=rtp.monitor

ciao

max
