[Gta04-owner] Routing UMTS sound

[Radek Polak]

Hi,
now that we have sound in 3.2 kernel, i'd like to do better UMTS<-->sound card 
routing.

I am now trying:

sox -r 8000 -t alsa hw:0 -t alsa -r 8000 hw:1
sox -r 8000 -t alsa hw:1 -t alsa -r 8000 hw:0

It works quite good except clicking noises every few seconds. Sox prints this 
error:

In:0.00% 00:00:51.71 [00:00:00.00] Out:410k  [ -====|====- ]        Clip:0    
sox WARN alsa: Input/output error

I have nearly zero experience with sound. Anyone has ideas what is the 
problem?

Thanks

Radek
