No sound in KDE
Since the May 19th upgrade of MPlayer, I have no sound anymore in KDE.
I'm running Slackware64-current Multilib (irrelevant here AFAIK) with KDE 4.8 (first AlienBob's packages, then stock packages) and phonon-mplayer as the KDE sound engine. My video player of choice is VLC from AlienBob's package.
I have a NVidia GT520 with NVidia prorietary driver from SBo packages with version bumped to 295.59 since the X and kernel upgrades in -current.
I plugged my TV to the HDMI output, and I extend my desktop with NVidia Twinview to watch VLC video and audio on the TV.
Before the upgrade, I had KDE sounds (login and logout jingle, notifications chimes, etc.), Amarok played my music, and in VLC I could switch the hardware audio output on the fly (HDA stereo to HDA 5.1, HDA to HDMI, HDMI back to HDA, etc.) to send the audio part to the TV.
Since the upgrade, I have no KDE sound anymore : no login and logout jingle, no notification chime, and Amarok skip through the playlist and stops saying "too much audio errors".
In VLC, I still have sound, but I can't switch the audio ouput anymore : it mutes, and I have to restart VLC (sometimes with using kill -9) to get the sound working again.
Here's everything I tried.
Compiling MPlayer and phonon-mplayer
I tried every combinations : stock phonon-mplayer recompiled against the stock new MPlayer, up-to-date phonon-mplayer compiled against the stock new MPlayer, stock or up-to-date phonon-mplayer compiled against MPlayer upgraded to 1.1 and ffmpeg-0.11, with a few tweaks of the Slackbuild and with or without a bunch of optionnal MPlayer external libs installed through their SBo SlackBuilds ...
However, it does not change anything, I still have no sound in KDE and Amarok.
Switching to phonon-vlc
I first installed AlienBob's package, then I compiled both 0.5 release and a up-to-date version from git.
In every case, KDE fails to even see it : it is not listed as a possible sound engine.
Switching to phonon-gstreamer
I get KDE audio back, and only KDE audio.
Amarok plays my music only because I installed the necessary plugins from AlienBob's packages (gst-plugins-bad and gst-plugins-ugly).
But I have no sound whatsoever in any other app, including VLC, MPlayer, audacious, flash in Firefox, and even pidgin notification sounds.
So phonon-gstreamer is a NO-GO.
Switching to phonon-xine
I get only KDE sounds, since it seems to lack the necessary parts to play MP3 in Amarok. And I have no audio in others apps like with phonon-gstreamer.
So phonon-xine is also a NO-GO.
Upgrading VLC from 2.0.1 to the 2.0.2 package AlienBob's released recently doesn't change anything either.
Do you have any lead or advice to solve this?
