Yeah, it looks like the upgrade did install some stray, unwanted
pulseaudio stuff, god only knows why. So now aplay & co. work fine, but jackd
still doesn't. It says:
Failed to acquire device name : Audio0 error : Invalid argument
Audio device hw:0,0 cannot be acquired...
Jack: ~JackDriver
Cannot initialize driver

This is for my builtin hda-intel card, but the end-result it more or
less the same for hw:1,0, which is my external USB soundcard. All of
this used to work flawlessly before the upgrade and the kernel/drivers
are the same. Any ideas?

Cheers,
S.M.
