After emerging newest version of media-libs/alsa-lib-1.0.14a-r1 there is no sound in programs working with pcm driver. Addressing the hardware device is still working. The program output in that case: ALSA lib dlmisc.c:118:(snd_dlsym_verify) unable to verify version for symbol _snd_pcm_empty_open ALSA lib pcm.c:2108:(snd_pcm_open_conf) symbol _snd_pcm_empty_open is not defined inside (null) MADPlug-Message: failed to open audio output: XMMS reverse compatibility output plugin To avoid this issue is necessary to introduce following string into the make.conf : ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" Actually not every plugin is needed, but using the whole string will avoid any similar potential issues. More about introduction the variable ALSA_PCM_PLUGINS could be found on that page: http://archives.gentoo.org/gentoo-dev/msg_141487.xml P.S. It was not really a nice solution to spare two more bytes on the hard drive . Please, think about reliability before you'll try to save place on my storage. Reproducible: Always Steps to Reproduce: 1. emerge media-libs/alsa-lib-1.0.14a-r1 2. having no fun. Actual Results: Upadate the world with ~x86 keyword. Expected Results: Including all alsa plugins by default.
