I've enabled libsamplerate ALSA plugin (from alsa-plugins ebuild) to upgrade weak ALSA linear resampler to something better with this /etc/asound.conf file: defaults.pcm.rate_converter "samplerate_medium" Sound works in all applications (aplay, gstreamer: quodlibet) except Flash plugin in Opera. The problem goes away if I disable the plugin. I suppose it would happen with any non built-in ALSA plugins. Reproducible: Always Steps to Reproduce: 1. Enable any ALSA plugin (e.g. libsamplerate) 2. Enter page with Flash playing sound Actual Results: No sound. Messages in the console: ALSA lib pcm_rate.c:1325:(snd_pcm_rate_open) Cannot open library for type samplerate_medium Expected Results: Play sound correctly. I've tried adding /usr/lib/alsa-lib to LDPATH to no avail. Probably either Opera or its launching script override that.
We can't fix neither flash nor Opera, take this upstream.
