snd_pcm_open fails

snd_pcm_open fails

[Frank W. Miller]

Hi,

I've got my header file installed now.  I had to install two rpms

alsa-lib-1.0.4-12.rhfc1.at.i386.rpm
alsa-lib-devel-1.0.4-12.rhfc1.at.i386.rpm

on my default Fedora Core 1 install.  I restarted and my cdplayer is 
still working so thats good.  I can also do my compiles with 
<alsa/asoundlib.h> being found and -lasound being linked, so thats good 
too.  Trouble is, now when I try to open the pcm devices with something 
like:

snd_pcm_open(..., "default", ...);

I'm getting a No such file or directory error.  Same thing for "plughw" 
and "plughw:0,0".  Anyone seen this before?

Thanks,
FM

Most likely missing ALSA device files (/dev/snd/*).  There's a script
somewhere to create them.
