Ok, now to come back to my problems with the Swissonic / Terrasoniq TS22 card.
Yesterday I checked the other cards I got in another Linux system, using the same base system, but on x86. In these systems the cards work perfectly, using "model=phase22". The server we've been talking about before is an amd64 system.
Suspecting a hardware problem with this individual card I replaced it, but the problem persists with other cards which worked fine in the x86 systems. I also copied over /etc/modules.d/alsa, /etc/asound.conf and /var/lib/alsa/asound.state from the other system - just to be sure.
But it doesn't help - I still just get a terrible noise. You might want to check it on http://radio.kanal-ratte.de:8000/rkr.ogg.
So there has to be a kind of a bug on amd64 systems...
Any ideas? The original Phase22 worked fine before the incident...
Greets,
Manuel
