Max volume very low (oss)

I'm using a laptop and oss. I installed ossvol and mapped the volume keys to it and it works, but the maximum volume is much too soft. (Much louder on windows.) Can it be overridden?
I tried using alsa but it never worked, so I use oss. Running alsamixer gives me the error

ALSA lib ctl_oss.c:398:(_snd_ctl_oss_open) Cannot open device /dev/mixer
cannot open mixer: No such file or directory

A bit of info about my sound card: (from lspci)

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)

Re: Max volume very low (oss)

Is your user in audio group?
Run 'modprobe snd-pcm-oss' as root and try running alsamixer again.

Re: Max volume very low (oss)

When doing 'modprobe snd-pcm-oss' it tells me the module isn't found, which is weird, because I've installed the alsa-oss package. I just reinstalled all the alsa packages and everything's the same.
And yes I'm in the audio group.

Re: Max volume very low (oss)

What's the output of

pacman -Q linux
ls /lib/modules/3.0-ARCH/kernel/sound/core/oss/snd-pcm-oss.ko.gz

Re: Max volume very low (oss)

linux 3.0.4-1

/lib/modules/3.0-ARCH/kernel/sound doesn't exist, much less any subdirectories.

Re: Max volume very low (oss)

That file is provided by linux package, maybe reinstalling the kernel will help?

Re: Max volume very low (oss)

Thanks - reinstalling the kernel's done some good and I'm almost there. Sound mostly works, but oddly, chromium is muted. I'm also having trouble setting the volume control keys. The examples I find involve commands along the lines of

amixer -q sset Master 2

but the output of that is

amixer: Unable to find simple control 'Master',0

And what's more, alsamixer resets the volume levels to 100% whenever I close it. For once, I'm afraid of waking people up!
