Mixer problems RELENG_5

I have no idea how long it's been like this for as I've only just 
noticed but it appears the mixer settings no longer have any effect at 
all on my soundcard volume. It's permanently at full volume no matter 
what I set the mixer values to.

I know the mixer used to work fine previously when I have changed the 
volume in XMMS etc but I only just noticed it doesn't any longer.

It's possible it's since the change from pcm to snd. Seems like roughly 
a similar time I think when I last remember it working.

I have a soundblaster live! in the machine, however there is also a 
onboard sound chip on the motherboard but the bios disables this when it 
detects the soundblaster. Sound is working fine apart from the volume issue.

This is with the latest sources from RELENG_5 as I have just done a 
buildworld dance this morning.

Relevant kernel stuff:

device          sound
device          "snd_emu10k1"
