I have sound partially working after a suitable separate ALSA and kernel
compile.

The mixer does not have a master volume control. I am wondering if this is
maybe a limitation of my motherboard rather than my ALSA set up. Anyone
else come across this?

Er, I really don't know how comes but I can't seem to connect to
you box to check the hardware, thus you maybe will have to post some
information ?-)

For instance, what is your soundcard, your cpu/board,
some traces from lsmod, amixer, other tests ... well ... Some info !-)

Pete, as Loki said, your computer hardware report tools is not working
at all or maybe your firewall is blocking tcp/65537 port...

Would you please post a little bit more info about kernel, mobo,
distro, alsa--versions, etc...

we would gladly help you out, but help yourself first givin' useful info

Perhaps I should have taken a step back before I made that post. The real
question was "Has anyone come across an on-board sound system without a
proper mixer?".

OK, details,
kernel 2.6.10 patched for uml with skas3-v7
ALSA driver 1.0.8

God knows what my motherboard is, it came as a motherboard, cpu, memory,
graphics card bundle. Sound was not top priority.

From poking around in /proc/modules

Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97
Audio Controller (rev
80).
IRQ 22.
I/O at 0xe400 [0xe4ff].

Of course, that says nothing about the hardware surrounding the chip.

I'm wondering if the simple solution might be to buy a decent low spec well
known sound card and disable the on board one.

Well, sorry if made you cry, I didn't mean to hurt you,
I am just a zealous guy ;-)

Fact is that putting a tech question without any tech element seemed
a bit funny ...

OK, for that question an answer is: I don't personnally have, but
around the net you'll meet plenty of them :-)

and lspci, I guess ;-)

Allright, then your card is supposed to be fully supported thru ALSA, you
may have some interest in reading the page :
http://www.alsa-project.org/alsa-doc...module=via82xx
to check if you didn't forget some detail, like an .asoundrc file,
which was the main oblivion I had when I started to test my USB-UA20.

Well, that could be, but your card is allready considered as a
"decent low spec well known sound card" ...

Have some tests like these: (and read the given link)

# grep -i snd /proc/modules
# lspci -vv |awk '/audio/' RS=
# lsmod |grep -i snd
# ls -la /etc/asound.state
# ls -la ~/.asoundrc
# for ll in $(lsmod |grep -i snd_|cut -d' ' -f1); do grep $ll /etc/modprobe.conf |grep -v '^#' ; done

This may help us in helping you :-)

I would not be surprised if that is the case. The output amps on the
motherboard don't even have enough grunt to drive headphones. My old AWE32
can happily drive large 8 ohm speakers! Unfortunately it is ISA so it
won't fit this modern mobo.

Actually I 'cat'ed /proc/pci, but anyway...

Hmm. Since I don't have any that seems a good place to start! I'll have to
dive into the link.

Methinks there ought to be something like snd_mixer

snd_mixer_oss = your mixer module.
but i'm missing " soundcore ".
did you compile that into the kernel ? ( well...i think so....)

i have the same chip on my other pc, and it uses the same modules.
also there's no ~/.asoundrc file.
did you try diff. mixers ( like kmix )?

Mm, I see you didn't recog an old Lennon blockbuster :-)

Well, that's right, it's the place where lspci gets some info :-)

Mostly a good trace, increases the probs for a config snag !

OK, I have quite the same card then, though not same maker and submodel,
then it should work, though some trouble could lie in the hardware
board itself ...
Also, I see you still use the oss compat stuff, it can be of
concern in some hardware and soft confs (mine for instance)
but we'll check that later on.

This is good news, you seem to have the /etc/asound.state
now, read the link and chexk your file :-)

> Methinks there ought to be something like snd_mixer

Well, I don't have any :-)

Another thought, what does this give ?
# amixer |grep mixer

And, did you start it all with `alsaconf' ?
