alsa-*-1.0.16 is stable on amd64. alsa-*-1.0.16 has been introduced in emul-linux-x86-soundlibs-20080418 which is still ~amd64. Older versions break stuff, e.g. 32bit games on amd64. Reproducible: Always Steps to Reproduce: ( This procedure is used since this is the only 32 bit game I play using alsa - probably there are even more 32 bit games using alsa that will fail ) 1. emerge enemy-territory 2. setup et-sdl to play enemy-territory using alsa sound http://nullkey.ath.cx/~stuff/et-sdl-sound/ 3. Use stable emul-linux-x86-soundlibs Actual Results: No sound output complainging about some wrong format problems Expected Results: Sound output Upgrading to emul-linux-x86-soundlibs-20080418 fixes the problem and brings back sound.
Done!
