GStreamer | don't know | Ver: 2.16.5
Summary: Hissing and poping on playback under heavy CPU load
Product: GStreamer
Version: HEAD CVS
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: don't know
AssignedTo: gstreamer-maint at bugzilla.gnome.org
ReportedBy: nesscg at mcmaster.ca
QAContact: gstreamer-maint at bugzilla.gnome.org
Play a vorbis or mp3 media in Rhythembox.
I'm not sure if it is the core/plugin/sound card but xmms does not have any
problems playing the files under heavy load.
I was using the FreshRPMS.net packages but they were old so I compiled from
source to try and see if this would solve the problem, but it did not.
The "hissing and popping" really sounds like I connected my analog sound
speakers to my digital output. You know that fuzz sound.
My System Info:
Intel i810 soundcard (onboard Toshiba Laptop)
2.6.4 kernel.org source compile
