The onboard sound on my current box is not that great, so I'm using my good old Soundblaster 128 (a.k.a. Ensoniq 1371). This thing has great sound quality... But it has no hardware mixing capabilties at all. Dmix ought to kick in by default for cards like that in ALSA 1.0.9, but it ain't working, and refuses to work no matter what I put in /etc/asound.conf or ~/.asoundrc. Is there a reliable way of getting dmix to work, or is it as good as broken?
