Reverting to alsa 1.0.11 and running alsaconf fixes this problem, so something in 1.0.12 isn't creating a dmix file. Running on the ca0106 driver, again I can revert to 1.0.11 and dmix will work again, going back to 1.0.12 and I lose dmix. Back and forth, gaining and losing dmix...
Sorry, this should be major as it breaks a feature necessary to run sound apps simultaneously
I talked on #alsa on freenode yesterday, where one of the users made me aware of that fact that dmix is taken care of by alsa-lib. Reverted to alsa-lib 1.0.11 and dmix is back, alsa-utils and alsa-driver and alsa-headers are still 1.0.12. So something in alsa-lib changed between 1.0.11 and 1.0.12 that doesn't allow dmix to work correctly, at the very least with my ca0106 driver.
Give a try to 1.0.13_rc1. At least here 1.0.12 works as a charm.
1.0.13, same problem, reverted to 1.0.11 and i'm fine again.
Update: I looked aroudn the gentoo forums a bit today to see if anyone else had this same issue...I found a thread that looked like the same issue, and the OP said removing /etc/asound.state fixed his problem. Sure enough, I emerged 1.0.12 for alsa-lib, utils, headers and driver, and dmix is working now after removing asound.state. So maybe a one-liner patch to rm -f /etc/asound.state ? Either way I have xmms and mplayer running simulataneously with dmixed sound, so it looks like asound.state was the problem.
I've got problems with alsa 12 too. Dmix was't working, even if I deleted the asound.state file and creating an asoundrc didn't help either. Downgrading alsa-lib to 11 solved the problem. I've kept all the other alsa packages from alsa 12. I have alsa-drivers, not alsa from the kernel and I'm using the cmipci module.
I take back that last comment about it working now. xmms and mplayer could play simulataneously, but wine couldn't do crap with dmix. So this morning I went back down to 1.0.11 and viola dmix in everything works now, including wine.
Palcek which driver are you using? From version 1.0.10 onward, dmix is enabled by default by -lib and -driver on their own, without configuration files. If it does not work, it's either trying to use the hardware mixing with a 2-mixing channels card (that obviously after two applications are open finishes the space for hardware mixing), or for some reason dmix fails to be enabled; in this case you should probably report it upstream. In particular, try to launch more than one time aplay -D plug:dmix somefile.wav and see how many can be launched at the same time.
Switched to in-kernel drivers for 2.6.17-gentoo-r8, problem is back as far as wine goes. Might be a wine-specific issue, I'm not sure
I'm closing this, the wine problem is bug 148102 . Removing asound.state should be done manually so the user knows their channels are going to be muted, etc., I'm closing this as wontfix
