If you start the mixer and turn down inputs one by one is the noise coming from an input line (line in, mic, etc...) ? With the KMix application, "Advanced" controls, either - deselecting "IEC958 Input Monitor" or - deselecting "Surround Down Mix" makes the noise disappear! Only if both are "on" (green LED simulation) the noise is present. The Microphone slider control on the "Input" pane does not have any effect at all. The Microphone slider control on the "Output" pane is at Max. and cannot be moved at all (also it does not have a green LED simulation). N.B. Thanks, this makes the system usable for me now. Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Description of problem: Lots of "clicking" noise on sound output. This is continuous. It starts immediately when the snd-intel8x0 module is loaded. When you play music, e.g. with "play test.wav" the music can be heard although it almost drowns in the noise. Sound is OK when running Redhat9. Logging in with the graphical screen starts the noise. If you log in with the console then there is no noise initially (because the snd-intel8x0 modules is then not loaded yet). Noise starts after loading the snd-intel8x0 or when playing music. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.log in 2. 3. Actual Results: Noise starts. Also after some time an error message dialog box comes that says the sound server will be disabled. The noise still continues afterwards. Expected Results: No noise. Additional info: The computers is a Dutch "Aldi" PC, built by Medion. It has an MSI motherboard with an SiS648 chipset (P4, 2.6GHz) === last two lines of "dmesg" output: intel8x0_measure_ac97_clock: measured 49641 usecs intel8x0: clocking to 48000 === snippet of "lspci -vvv" 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0) Subsystem: Micro-Star International Co., Ltd.: Unknown device 7010 Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 (13000ns min, 2750ns max) Interrupt: pin C routed to IRQ 3 Region 0: I/O ports at e400 Region 1: I/O ports at e800 [size=128] Capabilities: [48] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME-
