Various GNOME apps refuse to play sounds when configured to use the ALSA plugin provided by media-plugins/alsaequal-0.4. While vlc, gnome-mplayer and alsaplayer work fine, GNOME system sounds are not played, and rhythmbox remains silent. The following message is printed repeatedly to xsession-errors / standard error: ALSA lib pcm.c:2171:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_equal.so Reproducible: Always Steps to Reproduce: 1. Install and setup alsaequal. I've attached a sample .asoundrc file. 2. Make sure alsaplayer works; its sound output should be affected by changes to equalizer levels ("alsamixer -D equal"). 3a. Run rhythmbox and try to play music. 3b. Alternatively, do some actions that should trigger system sounds, e.g. opening the GNOME menu, closing a window or logging on/off. Actual Results: In step 3, no sound at all. Expected Results: Make some noise. The Makefile of media-plugins/alsaequal-0.4 has to be patched: < LDFLAGS := -O2 -Wall -shared --- > LDFLAGS := -O2 -Wall -shared -lasound This has fixed the problem for me.
