   There are oh so many places where this problem could be getting
created. I'll start here at the Planet and see if anyone here has seen
anything like this.

   I have made lots of headway this evening on the audio side of things,
having recorded and played back a number of things. Everything seems to
be working in one manner or another. So, on to MIDI.

   In the past you suggested I use pd which worked nicely for testing
simple MIDI functionality. I did that this evening with not so good

[mark@Godzilla mark]$ su -
[root@Godzilla root]# pd
ALSA lib pcm_hw.c:866:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed:
Device or resource busy
snd_pcm_open (output): Device or resource busy
snd_pcm_hw_params_set_access (input): Invalid argument
Sample width set to 4 bytes
ALSA: set input channels to 14
ALSA lib pcm_hw.c:297:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS
failed: Device or resource busy
snd_pcm_hw_params (input): Device or resource busy
pd: pcm.c:4907: snd_pcm_sw_params_current: Assertion `pcm->setup'
[root@Godzilla root]#

At this point, all I've done is warm boot my machine, start KDE, open an
xterm, su to root and type pd.

Any ideas? I looked at the pd web page for bugs and what not but didn't
see anything.

Any feedback you can provide is greatly appreciated..

Thanks in advance,
