Low volume sound on Dell Precision 530 (snd_ich)

Hi,

I've just started running RELENG_5 after having run RELENG_4 for a while.

After upgrading to 5.3-BETA3 (fresh install from ISO), the sound volume is
very low.  Running recent sources doesn't change things.

I did have a similar problem with RELENG_4, but I could work around it by
explicitly loading snd_ich rather than snd_pcm.  Unfortunately, that isn't
helping with 5.3-BETA.

This is a Dell Precision 530 with an i860 chipset.

Has anyone seen this before?  Any suggestions?

Thanks,

Jan Mikkelsen
