audacity crashes when trying to record

[violinStringC]

Please could you advise me on the following problem, bearing in mind I am a novice:

I have a new system running fedora c9 with kernel 2.6.25.14-108
I have installed audacity
yum -v --nogpgcheck install audacity-1.3.2-21.fc9.x86_64
and
rpm -ivh oss-linux-v4.0-1016.x86_64.rpm
(all libraries and other pre-requisites were successfully set up).
I have an M-audio Delta-66 sound card installed with the external Omni i/o AtoD
I learnt that audacity needs OSS-Linux.
I can get Audacity to generate a chirp or tone and hear it on my headphones plugged
into the external Omni i/o box.
But when I try to record - audacity crashes with the message:

audacity: src/hostapi/oss/pa_unix_oss.c:1615: PaOSS_AudioThreadProc: Assertion `frames == framesAvail' failed.

[1]+ Aborted sudo audacity

By way of history: I separately tested OSS (osstest) and got to hear the test sound
from the headphones on the front of my PC box. (Open Source Sound has the drivers for the M-Audi Delta-66 card)
I had previously installed audacity (before installing the M-audio Delta-66 sound card and OSS-Linux) and
was able to import mp3 files and play around in audacity as expected, but now crashes with the message

audacity: src/hostapi/oss/pa_unix_oss.c:1651: PaOSS_AudioThreadProc: Assertion `frames == framesAvail' failed.

If I uninstall OSS-Linux then audacity does not know about any audio devices.
Thank You.

Have you tried running it with ALSA instead of OSS?

Thank you SteveThe Fiddle

I had not tried the ALSA package. I have just gotten back to this job and have installed the ALSA-driver,
ALSA-Lib, ALSA-utils and ALSA-oss according tot he instructions found on the wiki
http://alsa.opensrc.org/index.php/Quick_Install
and all seemed to go without a hitch. However I've got stuck at step 4
<snip>
4. Loading the ALSA modules
Now insert the modules into the kernel space. [WHAT DOES THIS MEAN?]
modprobe snd-ens1371
modprobe snd-pcm-oss
modprobe snd-mixer-oss
modprobe snd-seq-oss
<end snip>

Entering command modprobe, lsmod etc the commands are unknown to my fedora core 9 (kernel 2.6)
I do find files at
/etc/modprobe.conf
/etc/modprobe.d

Please advise me how to proceed before testing audacity with ALSA.

thanks.

Okay - I have one answer for myself - as a slightly more experienced novice - about installing modules into the linux
kernel. The modprobe is not a shell command but is located in /sbin.
thus

[[email protected] alsa-oss-1.0.17]# /sbin/modprobe snd-ens1371

generates the errors:
[[email protected] alsa-oss-1.0.17]# /sbin/modprobe snd-ens1371
FATAL: Error inserting snd_pcm (/lib/modules/2.6.25.14-108.fc9.x86_64/kernel/sound/acore/snd-pcm.ko): Unknown symbol in module, or unknown parameter (see dmesg)
WARNING: Error running install command for snd_pcm
FATAL: Error inserting snd_ens1371 (/lib/modules/2.6.25.14-108.fc9.x86_64/kernel/sound/pci/snd-ens1371.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Can anyone help me here
thanks.
