that happens with: last.fm client, flash10 beta (youtube.com). never happens: amarok. That happens time to time. Killing X by Alt+Ctl+Backspace few times can solve problem. Noise come from left speaker independ i use my notebook speakers or headphones. It looks like a PCI DMA timing related problem. It would be probably difficult to solve it. look like it solved in 2.6.27 build. i continue playing with development kernel... happens again. just not all time reproducible. suspend/resume can temporally fix this issue (until next boot). This problem also happens on latest x86_64 Fedora 11 with 2.6.29.6-217.2.3.fc11.x86_64 kernel. I have also upgraded alsa-drivers to 1.0.20, but the problem remains. The board is stock Intel D975XBX [1]. Before upgrading to F11, there was no static on the left channel, but when alsa kernel drivers were upgraded to 1.0.20, static is always heard on left channel (i.e. I was not able to "fix" the problem by rebooting computer). Since PCI timings are suspected, here is output for HDA PCI device: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) Subsystem: Intel Corporation Device 0417 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 22 Region 0: Memory at e0400000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel Info, generated from alsa-info.sh will be attached in the next message. FYI, the same bug is reported on Ubuntu [2] and is already tracked at ALSA development site [3]. Since the problem happens in F11 all the time, I think that the severity of this bug should be raised. This bug is really (__REALLY__!) annoying, it effectively strips "HD" from HDA ;) Perhaps some additional info is hidden in the output of "alsactl init 0": Unknown hardware: "HDA-Intel" "SigmaTel STAC9221D A2" "HDA:83847683,80860417,00103201" "0x8086" "0x0417" Hardware is initialized using a guess method BTW: The sound works without _ANY_ problem in WindowsXP. (I can provide furhter info / debug on request. Also, I can change and recompile drivers if this will help. IMO, PCI protocol analyser is of little use in this case ...)

This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
