Hi. I'm reporting here a problem with the emul-linux-x86-soundlibs on amd64. The problem is that 32 bit apps can not use the sound device when 64 bit apps are using it, and viceversa, when using software mixing (aka dmix). When only one "kind" (32 bit or 64 bit but not both) of application uses the sound device software mixing works ok. I've tracked down the problem. The 32 bit libraries that are required for software mixing are not included in emul-linx-x86-soundlibs (I've tested only version 2.4). The missing libraries are: smixer-ac97.a smixer-ac97.so smixer-hda.la smixer-sbase.a smixer-sbase.so smixer-ac97.la smixer-hda.a smixer-hda.so smixer-sbase.la and should be in the alsa-lib/smixer (/emul/linux/x86/usr/lib/alsa-lib/smixer) folder from where libasound.so.2 is installed (/emul/linux/x86/usr/lib) Placing 32 bit binaries of alsa-lib and the smixer libs from an RPM for anther distribution (alsa-lib version 1.0.13, which matches the native 64 bit version that I have) under /emul/linux/x86/usr/lib fixed the problem in my case. For example, I'm able to have audacity (64bit) playing mp3s while I'm talking to someone else through skype (32bit), something that didn't work before. I don't think that this bug is an issue for people with cards with hw mixing support in alsa, but I think that many will benefit from the addition of the 32 bit smixer libraries to the emul-linux-x86-soundlibs ebuild. Finally, I think that this bug is related to bug #148102 to some extent. --Juan

can you post the libs you are using?
Created attachment 103584 [details] The 32bit smixer libs for emul/alsa-lib
(In reply to comment #2) > can you post the libs you are using? > Sure, see the attachment. Unfortunately I deleted the rpm that was the source of the libs... so no way to know their original source.
I have updated alsa-lib to 1.0.14_rc1 and added its smixer libs in emul-linux-x86-soundlibs-2.5. Try this please and reopen if you have any problems.
