[pulse] Latency issues
Last modified: 2009-04-14 17:26:46 UTC
Moved from http://pulseaudio.org/ticket/270: Encountered some issues in GST-pulse when using gnome-sound-properties and gstreamer-properties. Not sure how to explain them as i'm quite a novice, so i'll just attach the output of gnome-sound-properties --gst-debug-level=3 and hope its self-explanatorly. The symptoms being: If I select 'pulseaudio sound server' as my sound input with my usb mic set as the default source in pulseaudio and press test, it plays the microphone output for a fraction of a second and then quickly degrades, and then is silent. and i get a series of output similar to: 0:00:03.501275672 11042 0x84fe3b0 WARN baseaudiosink gstbaseaudiosink.c:919:gst_base_audio_sink_skew_slaving:<autoaudiosink0-actual-sink-pulse> correct clock skew -5963085 < -5000000 Talked to some of the folks in #gstreamer on freenode about it and they had the following to say: <wtay> rikai, yeah, something with pulseaudio and latency, it needs fixing at some point <rikai> wtay, ahh, so its a known issue then? <wtay> rikai, yep <rikai> wtay, any chance you could point me in the direction of the bug report? I'd like to keep tabs on it. <wtay> rikai, there is no bug report for it yet <rikai> ahh, so its a new issue too, then? That explains why it just started happening recently. <rikai> so, is the problem gstreamer-side or pulse side? i'd think it'd be in gst-pulse, which is gstreamer side, correct? Sorry for asking so many questions, i just want to know where i should follow any progress and such. <wtay> rikai, pulse side, likely. I think the gstreamer side should do things right..}}}

I am also experiencing exactly the same issue.

I'm having the exact same problem as described above; with gnome sound properties set to capture from pulseaudio I hear my mic for a fraction of a second then silence. I'm using Ubuntu 8.10 with current updates and if it helps, this is my sound card configuration: 0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4 Intel 82801DB-ICH4 with STAC9752,53 at irq 11 2: : timer 3: : sequencer 4: [ 0- 4]: digital audio playback 5: [ 0- 3]: digital audio capture 6: [ 0- 2]: digital audio capture 7: [ 0- 1]: digital audio capture 8: [ 0- 0]: digital audio playback 9: [ 0- 0]: digital audio capture 10: [ 0] : control Naturally, if anyone needs more information please let me know, I'd be more than happy to oblige.
Should be fixed with the pulsesink rewrite that will be in -good 0.10.15. Please retest and reopen if it does not work for you.
