My KDE and PulseAudio version are:
| Code: |
kde-base/kdelibs 4.4.5
media-sound/pulseaudio 0.9.21.1
net-im/skype 2.1.0.81
|
I've gone through all the pulseaudio setup steps, and generally speaking the sound works fine across the board - except that it's extremely laggy.
I've looked in:
http://www.pulseaudio.org/wiki/PerfectSetup
And added the lines:
| Code: |
default-fragments = 8
default-fragment-size-msec = 5
|
to my daemon conf, but still.. no improvement.
Is anyone else experiencing laggy sound with this sort'a setup?
Does it work well for anyone? A copy of your configuration files would be greatly appreciated..
Is there any other useful information I could post regarding this issue?
Thanks |
