I'm writing in a mood of some frustration, so please bear with me.
All I want to do is transfer a sound-recording from a tape to disk so
that I can edit it, clean it up, and burn it to a CD.
My system is Debian testing, with kernel 2.4.23 with the ck1 patches
for low latency and preemption. It works very nicely. Alsa is:
alsa-driver-1.0.0rc2.tar.bz2
alsa-lib-1.0.0rc2.tar.bz2
alsa-tools-1.0.0rc2.tar.bz2
alsa-utils-1.0.0rc2.tar.bz2
compiled and installed without complaint or error messages. The
sound-card is a Turtle Beach Santa Cruz. The CPU is:
model name : AMD Athlon(tm) Processor
stepping : 2
cpu MHz : 748.877
cache size : 512 KB
When I start, for instance, aplay or alsamixer, lsmod reports these
modules as being loaded:
Module Size Used by Not tainted
snd-pcm-oss 37860 0 (autoclean)
snd-mixer-oss 13008 1 (autoclean) [snd-pcm-oss]
snd-cs46xx 71240 1 (autoclean)
snd-pcm 61764 0 (autoclean) [snd-pcm-oss snd-cs46xx]
snd-timer 15716 0 (autoclean) [snd-pcm]
snd-rawmidi 14752 0 (autoclean) [snd-cs46xx]
snd-seq-device 4336 0 (autoclean) [snd-rawmidi]
snd-ac97-codec 47340 0 (autoclean) [snd-cs46xx]
snd-page-alloc 6388 0 (autoclean) [snd-cs46xx snd-pcm]
snd 32996 0 (autoclean) [snd-pcm-oss snd-mixer-oss snd-cs46xx snd-pcm
snd-timer snd-rawmidi snd-seq-device snd-ac97-codec]
The tape recorder output is going into the (blue) Line-In jack on the
sound-card. To record, I do:
wavr -f 3.wav -r 44100 -d 16 -c 2 -s l
In alsamixer, all three of LINE, CAPTURE, and ADC are set to Capture,
and levels are set.
But what is puzzling and frustrating is that after recording, I can't
listen back to what has been recorded. In fact the ability to play
back is gone completely. Changing the mixer settings makes no
difference. Closing and re-starting the mixer makes no
difference. Using aumix rather than alsamixer makes no difference.
The only thing that seems to make a difference in this circumstance,
is to un-load all the sound-related kernel-modules by hand with rmmod
(a very tedious process because many initially report that a device or
resource is busy), and then call aplay or wavp again. Then the wav-file
will usually play again. Here I'm referring not to the wav-file I've
been attempting to record, but any wav-file at all, including ones
that play nicely in the general case.
This behaviour seems to be correlated with error messages like the following in
kern.log and sys.log:
Jan 4 22:26:32 toraigh kernel: PCI: Found IRQ 14 for device 00:0d.0
Jan 4 22:26:32 toraigh kernel: ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:\
416: cs46xx: failure waiting for FIFO command to complete
Jan 4 22:26:32 toraigh kernel: ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:\

Jan 4 22:35:10 toraigh kernel: ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:\
416: cs46xx: failure waiting for FIFO command to complete
Am I missing something obvious? Am I just stupid? I *am* frustrated.
Can anyone shed any light on this?
Thanks,
Jim
