Could someone reproducing the bug please compare (or attach) the output of: LC_ALL=C gst-launch -v filesrc location=xyz.ogg ! decodebin ! audioconvert ! audioresample ! alsasink and: LC_ALL=C gst-launch -v filesrc location=xyz.ogg ! decodebin ! audioconvert ! audioresample ! volume volume=1.0 ! alsasink (note -v flag)
as I wonder whether different caps are negociated in the two cases. The first pipeline should produce the problematic sound and the second shouldn't. In my case -- I don't get the crackling sound -- I see the second pipeline negociated with 32-bits audio samples instead of 16-bits on the whole pipeline: -/pipeline0/audioconvert0.src: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)32, depth=(int)32, rate=(int)44100, channels=(int)2 +/pipeline0/audioconvert0.src: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100, channels=(int)2 ... I guess this could be a GStreamer or Alsa issue for specific sample sizes; this is also suggested by the indication that using "pulsesink" instead of alsa seems to help some persons. If you see a difference, then please try replacing "volume volume=1.0" in the second pipe line with: 'audio/x-raw-int,endianness=(int)1234,signed=(boolean)true,width=(int)16,depth=(int)16,rate=(int)44100,channels=(int)2' (mind the quotes as otherwise your shell might be unhappy) if it doesn't crack with neither volume volume=1.0 or the above caps filter, then it's likely specific to the output mode and it would be useful to check with alsa output directly instead of GStreamer. -- Rhythmbox sound problems (clicking/snapping/crackling) when not using crossfading backend https://bugs.launchpad.net/bugs/116990 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
