Version: unspecified (using KDE 4.4.4) OS: Linux It's important for me because I watching movies with 5.1 surround sound, but, through bad 5.1 support in the ALSA driver, I can't play 5.1 if one of applications uses the sound device (or just do not release it, like dolphin does). As result, I am forced to close dolphin every time before playing a movie with the 5.1 sound, if I've previewed this movie previously in the dolphin information panel. Example: lsof | grep snd kmix 14718 heaven 11u CHR 116,10 0t0 3839 /dev/snd/controlC0 dolphin 14945 heaven mem CHR 116,8 3835 /dev/snd/pcmC0D0p dolphin 14945 heaven 24u CHR 116,10 0t0 3839 /dev/snd/controlC0 dolphin 14945 heaven 29r CHR 116,2 0t0 3595 /dev/snd/timer dolphin 14945 heaven 30u CHR 116,8 0t0 3835 /dev/snd/pcmC0D0p amarok 18261 heaven 13u CHR 116,10 0t0 3839 /dev/snd/controlC0 By the way, it's related to the all KDE applications I seen. Even knotify had this problem before and amarok too. I don't know, is it the global kde (phonon?) fail, or programmers simply don't know how it works? Reproducible: Always
Cannot reproduce using KDE 4.4.5. Could this be related to a wrong configuration on phonon?
You ask me? :) I only can assume, that this is related to the phonon backend (I use phonon-xine). Right now I've opened dolphin, selected a video file and launched its preview in the dolphin information panel. After I've stopped it and even closed this tab, dolphin doesn't released the sound device, until I not closed it. It's in KDE 4.4.95, but it happened and in 4.4.5 and in earlier releases.
Which Phonon backend do you use?
Xine backend.
Thank you for the feedback.
We are sorry, but the xine backend is unmaintained: http://lists.kde.org/?l=kde-announce&m=130744384419151 Please use the phonon-backend-gstreamer or thre phonon-backend-vlc instead.
