[pulseaudio-discuss] garbled mic input with padsp teamspeak

I'm trying to get teamspeak [1] working with pulseaudio via padsp. 
Teamspeak is a very old app which uses /dev/dsp. I've got no problems 
with audio output, only input.

The mic works fine in any other application and I even get good sound 
with audacity launched with padsp. I didn't expect that, I guess 
audacity detects the correct audio mode/fragments? Or maybe the problem 
is that teamspeak is a 32bit app?

But with padsp teamspeak I get bad sound from the mic. Without padsp the 
sound is OK, but as it uses OSS it blocks all other apps including 
pulseaudio. So need to get it to play ball with padsp.

I've tried playing around with default-fragments and 
default-fragment-size-msec. As it's two variables and I don't really 
understand what they do I haven't been able to get acceptable sound. 
Though better than the default. My best result is something like normal 
voice but with frequent hiccups.

If changing the default-fragment options is the way, could somebody 
please point me to some documentation that would help me find the 
correct values. If not, what else should I look for.

I'm running Fedora 9 64bit, all up to date, pulseaudio-0.9.10-2.fc9.x86_64.

The audio card is E-MU 0404 USB. It works out of the box with Fedora 9, 
though officially the alsa drivers are not completed yet.

I'm grateful for any input.
