failed on both machines, I thought I had a Redhat or kernel-2.4.9 or
operator problem that was common to both machines. But the xrun from
aplay appears to be a red herring. Other sounds pretend to play with
out generating errors.
The ens1371 finally started working last night. I happened to try
another device on the card, thus:
aplay -v -D hw:0,1 /usr/share/sounds/startup2.wav
this played audibly, and since then the default device works, too. Go
figure.
On the Toshiba/ymf744/ymfpci machine, no such luck.
Suggestions from the list were:
try the intel8x0 driver
(doesn't load, no such device)
try starting with nothing in modules.conf
(loads fine, makes no sounds)
I've upgraded the kernel to 2.4.17 with patch jl13-ll, same results.
It seems like everytime I look there's something new in the output of
amixer or alsactl, and some things are not initialized as muted. For
instance, there are these two controls:
control.36 {
comment.access 'read write'
comment.type INTEGER
comment.range '0 - 16383'
iface MIXER
name 'Digital Capture Volume'
value.0 16383
value.1 16383
}
control.37 {
comment.access 'read write'
comment.type INTEGER
comment.range '0 - 16383'
iface MIXER
name 'Digital Capture Volume'
index 1
value.0 16383
value.1 16383
}
which don't show up in alsamixer but do show up in mixers going
through the oss. They initialized at max volume and have been there
ever since.
The other thing which puzzles me is the output of
/proc/asound/sndstat. Right now it says:
------------------------------------------------------------------------
Sound Driver:3.8.1a-980706 (ALSA v0.9.0beta10 emulation code)
Kernel: Linux elf2.elf.org 2.4.17-jl13-ll #2 Thu Jan 24 01:47:22 MST 2002 i686

------------------------------------------------------------------------
Last night it listed the yamaha as an audio device. I have no idea
what "CONFIG" this message refers to, how I would config a sound card
without audio, or why the contents of sndstat seem to randomly change.
Thanks again to those who have tried to help. I've been trying to
make alsa-0.9.0 run on this machine for nearly a month, seeking help
for a week, and all I've heard from the speakers are an occasional
faint crackling when the driver loads, or a faint click when aplay
finishes a wave. The alsa-driver-0.5.12a ymfpci driver works, the
ymfpci driver in the current 2.4.* kernel works, and the osslinux396a
driver works.
But alsa-driver-0.9.0beta10 and subsequent cvs commits do compile, do
load without errors, do pretend to play sounds, do run the sequencer
interface, but do not make any audible sounds.
I'm happy to provide any information, to try any patches or
to attempt any experiments,
Patch to cvs/alsa-driver/Makefile appended which fixes the uninstall
target, though I'm not sure this is how you want to clean out the
kernel/sound directory.
