This problem seems similar to mine, on Kubuntu Jaunty and a HDA Intel ALC861. When I use Gstreamer Phonon engine, Amarok doesn't play anything at all, although other apps do.
When I switch to the Xine backend (the default one in Kubuntu) from systemsettings panel, then Amarok plays. But then, Amarok sound volume doesn't follow the KMix sound volume. By experimenting (Xine backend) I found out that Amarok "follows" the "Front" channel while KMix gives me only the PCM channel (the Front channel can only be muted, there's no apparent way to adjust it). I found a similar bug report in KDE bugzilla, but the developers say it's a Phonon issue. I' m not sure about that, since Amarok2 plays OK in Manriva 2009.1. See: https://bugs.kde.org/show_bug.cgi?id=189755 I run Kubuntu Jaunty with these packages installed: amarok 2:2.0.2mysql5.1.30-0ubuntu3 amarok-common 2:2.0.2mysql5.1.30-0ubuntu3 phonon-backend-gstreamer 4:4.3.1-0ubuntu3 phonon-backend-xine 4:4.3.1-0ubuntu3 libxine1-ffmpeg 1.1.16.3-0ubuntu1 gstreamer0.10-fluendo-mp3 0.10.7.debian-1 gstreamer0.10-ffmpeg 0.10.6.2-1ubuntu2 gstreamer0.10-alsa 0.10.22-5 ** Bug watch added: KDE Bug Tracking System #189755 http://bugs.kde.org/show_bug.cgi?id=189755 -- Bug 188444 – playback is unreliable and broken in Amarok and JuK using phonon gstreamer backend https://bugs.launchpad.net/bugs/351319 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
