I'm not the OP, but it's been my experience that, when things aren't configured to handle multiple processes using audio, you can't even pause a movie in, say, mplayer to check out the youtube video a friend just pointed you towards... which nowadays, is far from an uncommon thing for a person to expect their computer to handle. Lately, I've had zero issues with alsa pretty much configuring itself properly, given I'm using the in kernel alsa drivers for my systems... and it hasn't required any manual configuration of dmix or similar to function properly. Last time I used a separate sound daemon (aside from a short stent with Ubuntu on my netbook that, I think, had me using pulseaudio), I was running esound to manage audio from a headless box over my network... and ESD was playing nicely with other straight alsa apps on the same box. As a bit of a tip to the OP, since I'm going on about it all working, while for them it isn't... 1) make sure you're using the alsa drivers for your card and not oss (checking lspci -k) and 2) enable oss emulation in the kernel (makes even OLD oss based software work without much argument, in my experience). -- Poison [BLX] Joshua M.
