I'm not the OP, but it's been my experience that, when things aren't |
| 25 |
configured to handle multiple processes using audio, you can't even |
| 26 |
pause a movie in, say, mplayer to check out the youtube video a friend |
| 27 |
just pointed you towards... which nowadays, is far from an uncommon |
| 28 |
thing for a person to expect their computer to handle. |

Lately, I've had zero issues with alsa pretty much configuring itself |
| 31 |
properly, given I'm using the in kernel alsa drivers for my systems... |
| 32 |
and it hasn't required any manual configuration of dmix or similar to |
| 33 |
function properly. Last time I used a separate sound daemon (aside |
| 34 |
from a short stent with Ubuntu on my netbook that, I think, had me |
| 35 |
using pulseaudio), I was running esound to manage audio from a |
| 36 |
headless box over my network... and ESD was playing nicely with other |
| 37 |
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, |
| 40 |
while for them it isn't... 1) make sure you're using the alsa drivers |
| 41 |
for your card and not oss (checking lspci -k) and 2) enable oss |
| 42 |
emulation in the kernel (makes even OLD oss based software work |
| 43 |
without much argument, in my experience). |
