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.
