Can't here sound via application using gstreamer Reproducible: Always Steps to Reproduce: 1. System -> Preferences -> Sound 2. Sound playback: ALSA 3. Click "Test" Actual Results: audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open audio device for playback. Expected Results: Any sound. No sound in rhythmbox, totem. But there is sound in browser at YouTube (flash, no gstreamer) It is gstreamer problem, though. What can I do?

emerge gst-plugins-alsa That should solve your problem, i encountered the same problem today. I think the gstreamer ebuild should have a use flag "alsa" that depends on the gstreamer alsa plugins. Ill write a sample one right now and upload it in afew minutes.
I tried it already. And will try today, after full system rebuild.
The same situation =(
Please help me. Maybe some supposition?
What does this give you ? GST_DEBUG=alsasink:5 gst-launch audiotestsrc ! alsasink

You're alsa is not configure properly... see http://www.gentoo.org/doc/en/alsa-guide.xml
So why can I hear sound from netscape-flash? It is not using alsa? OK, I'll try to check the doc now, thanks.
1. Rebuild kernel with alsa support as a module with my sound card 2. alsaconf as root and my sound card selection, then: Running update-modules... * Updating /etc/modprobe.conf by hand ... [ ok ] * Updating modules.dep ... [ ok ] Loading driver... * Loading ALSA modules ... * Could not detect custom ALSA settings. Loading all detected alsa drivers. * Loading: snd_hda_intel ... [ ok ] * Loading: snd-pcm-oss ... [ ok ] * Loading: snd-seq ... [ ok ] * Restoring Mixer Levels... [ ok ] Setting default volumes... and OK. 3. At the reboot (alsasound at the boot runlevel) I see only snd-pcm-oss and snd-seq modules, not snd_hda_intel. The result: audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink profile=chat: Could not open audio device for playback.

sorry, but reopening
You have ALSA issues that you need to fix first. And netscape-flash is possibly the worst application to debug the problem. Please emerge mplayer with the alsa USE flag, or aplay, and use those tools to debug alsa. Once alsa works properly, and if gstreamer still fails, please reopen another bug. Thanks
ok, I'll try it at evening. thank you.
Don't know what it is =( Thanks.
