Analysis of play/stop of sound

Description Stefan de Konink 2009-01-26 01:53:52 UTC
I don't think there is a more clear way to describe the problem as subject. I'm running on 2.6.28-gentoo.

00:07.0 Audio device: nVidia Corporation MCP67 High Definition Audio (rev a1)

It is extremely annoying; I am able to stop the issue using alsamixer making the front channel going down and up in volume. If someone is really interested in what sounds, I could make an analogue recording of the actual sound, but I expect a buffer is not properly reset.

Reproducible: Always

Steps to Reproduce:
Comment 1 Tony Vroon gentoo-dev 2009-01-26 15:28:43 UTC
More information will be required before the kernel/ALSA teams can take a look at this bug:
- what codec is attached to said MCP67 HDA controller (/proc/asound/card0/codec#0)
- emerge --info
- the analog recording, please attach it in .wav format

Analysis of play/stop of sound

Do a spectrum analysis between the last two breaks, there is the bug most clear.

Was recorded as:
- PC to Receiver
- Headphone receiver to OLPC Mic-In (working on battery)
Comment 4 Stefan de Konink 2009-01-26 16:02:50 UTC
Everything is present :) Flac can be extracted in the usual way. Bugsize file limit is too small.
Comment 5 Pacho Ramos gentoo-dev 2014-05-18 09:34:34 UTC
What is the status of this with an updated system and a newer kernel?
