Description Sergei Andreev 2009-10-07 21:21:58 UTC

At the end of audiofile playback there is some distortion (in left channel - I can see it with ossxmix) and it specially annoying on short sounds like notifications or game sounds in KDiamond.
I am using phonon-xine-backend, with gstreamer-backend sound quality is terrible.

Didn't try mplayer or vlc backends though these apps play nicely standalone.

I can run xine-ui, but when I am trying adjust some settings xserver goes mad eating all available CPU then crash (I think this is fgrlx related)

Software:

Phonon 4.3.1 
xine-backend 0.2.60
OSSv4.1 - OSSv4.2
Mixer - vmix

Hardware:
M-audio Revolution 5.1 (envy24ht)
Frequency rate: 48000 Hz, switching to 96000 Hz did not help

Did I get this right, you were using the Phonon version from Qt 4.6.x when this happened? Is this still valid with latest KDE SC 4.4?

>Did I get this right, you were using the Phonon version from Qt 4.6.x

Not from Qt 4.6.x but some custom build.
I will check Phonon's behaviour again after upgrade to KDE 4.4.x / Qt 4.6.x

Comment 3 Sergei Andreev 2010-03-24 22:10:47 UTC

Qt: 4.6.2
KDE: 4.4.1 (KDE 4.4.1)
libphonon4: 4:4.6.2-0ubuntu1~karmic1~ppa2
phonon-backend-xine: 4:4.3.80-0ubuntu1~karmic1~ppa2
libxine1: 1.1.16.3-vdpau-0ubuntu2~karmic~nvidiavdpauppa1 (tested with usual xine 1.1.16.3 too 1.1.16.3)

Distortion still here.

Thank you for the feedback.

Comment 5 Myriam Schweingruber 2011-01-28 12:05:12 UTC

Is this still valid with a more recent Phonon version? Current stable is 4.4.4

Comment 6 Myriam Schweingruber 2011-12-01 09:01:52 UTC

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.
