I didn't spot this before, your card/driver likes a samplerate of
41000hz, but 44100 is probably what you want.

I would suggest using the <quality> tags and not the <nominal-bitrate>
tags as the latter forces managed modes, therefore higher CPU usage.

notice a slight mismatch here, 44100 expected but audio is actually
41000

this matches the actual input rate, but I guess you'll want to change
this as well.

<p>> The "login failed: success" message is especially cryptic.

again check the icecast log to see why the source is dropped.

That sounds like a race to connect type problem, make sure of the max
source count on icecast.
