Created attachment 571442 [details] emerge --info timidity++ Hello, It seems Alsa 1.1.8 threw out some old things. On top of having to remove some entries from my .asoundrc (it is empty for the following bug report!), it broke timidity. With alsa-lib-1.1.8: > timidity foo.mid Couldn't open output device > timidity -Os -iA foo.mid ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.1.8/work/alsa-lib-1.1.8/src/pcm/pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave Can't open pcm device 'default'. Couldn't open ALSA pcm device (`s') It plays fine on alsa-lib-1.1.6-r1. Tested with both timidity++-2.14.0-r3 and timidity++-2.15.0.
The similar problem on two machines. Speaker-test fails with alsa-lib-1.1.8: speaker-test -c2 -t wav speaker-test 1.1.8 Playback device is default Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) ALSA lib /tmp/portage/media-libs/alsa-lib-1.1.8/work/alsa-lib-1.1.8/src/pcm/pcm_dmix.c:1108:(snd_pcm_dmix_open) unable to open slave Playback open error: -16,Device or resource busy With 1.1.6 version it's OK
P.S. For me the solution was related to missing symlink: https://bugs.gentoo.org/681628 After it had been created the problem with speaker-test went away.
