I've decided that the only way I'm going to get my system to record
anything decent is to use jackd. But, I'm being a total idiot with
this ...

First off, I have the the following devices:

bob$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC883 Digital [ALC883 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: CODEC [USB Audio CODEC], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

The 2nd one is a spdif speaker attached to the mother board. For now,
lets try to get jack working with this.

pasuspender -- jackd -d alsa "ALC883 Digital"

(BTW, I tried hw0,1 and some other combinations ... but they are the
same results)

After the command I get:

bob$ pasuspender -- jackd -d alsa "ALC883 Digital"
jackd 0.121.2

JACK: unable to mlock() port buffers: Cannot allocate memory

**** alsa_pcm: xrun of at least 0.033 msecs

Which seems to be okay?

Now, I run audacity. Got jack as an output option and load a file.
Play it ... the VU meter shows, but no audio. NADA. Just silence.

If I can't get a simple play to work, I fear becoming a recording star
is out of my reach!

Please, this shouldn't be that hard???
