Hi all,

This is a fairly simple problem.

My asound.conf looks like:

		type hw
		card 1

but running:
	jackd -v -R -d alsa -d envy1

gives the output:

	getting driver descriptor from /usr/lib/jack/jack_dummy.so
	getting driver descriptor from /usr/lib/jack/jack_alsa.so
	jackd 0.95.6

	ALSA lib pcm.c:1954:(snd_pcm_open_noupdate) Unknown PCM envy1
	jackd: pcm.c:690: snd_pcm_nonblock: Assertion `pcm' failed.

Whats wrong here??
