[pulseaudio-discuss] pulseaudio / Alsa problem

[liebrecht at grossmann-venter.com]

I asked this question on the Alsa ug but it seems dead.
To me it looks like an alsa problem, but I ask here hoping someone would 
know what is going on.

Pulseaudio/Alsa used to work flawlessly with my 1818VSL, but it recently 
started to act up.

In order for me to get the sound going I have to issue pulseaudio from 
cli, and then wait about half an hour, where pulseaudio/alsa goes 
through several clicks and pops through the 1818vsl to get it going, 
rep-eating the same error I quote below.

Eventually the discrepancy is resolved between alsa/pulseaudio and the 
system works great then with 1818vsl as the soundcard.

As mentioned running pulseaudio from cli, I then get the following 
recurri9ng error scrolling with clicks and pops for half an hour after 
pulseaudio miraculously find the 18888vsl through alsa.
I cannot get info online or any means to resolve the Failed to load 
module "module-alsa-card" problem.
