From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.2; Linux) (KHTML, like Gecko) Description of problem: Fresh install of FC2, installer correctly detects sound card as Silicon Integrated Systems (SIS) chip (this is a laptop) and installs ALSA module snd_intel8x0. Once installed a high-pitched whine, very piercing, emits from the laptop's built-in speaker. Running xmms produces a "could not open sound device" error using the ALSA output driver. When I run the Soundcard Detection program, the high-pitched whine stops. I click "play test sound" but no sound comes out. The program appears to lock but after a very long time (~60 seconds) it asks me if I heard the sound. I know the audio works because it was working using the 2.4 OSS drivers in Red Hat 9, previously installed on the machine. lspci output: 00:00.0 Host bridge: Silicon Integrated Systems [SiS] SiS645DX Host & Memory & AGP Controller (rev 01) 00:01.0 PCI bridge: Silicon Integrated Systems [SiS] Virtual PCI-to-PCI bridge (AGP) 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS962 [MuTIOL Media IO] (rev 14) 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016 00:02.3 FireWire (IEEE 1394): Silicon Integrated Systems [SiS] FireWire Controller 00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] 00:02.6 Modem: Silicon Integrated Systems [SiS] AC'97 Modem Controller (rev a0) 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0) 00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 00:03.2 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 00:03.3 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller 00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet (rev 90) 00:09.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller 01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 440 Go 64M] (rev a3) Version-Release number of selected component (if applicable): kernel-2.6.6-1.427 How reproducible: Always Steps to Reproduce: Reboot and/or run the soundcard detection. Additional info:
As an additional twist, I realized that the whine only starts when entering KDE. I turned off artsd thinking that was the culprit, but it made no difference. rmmod snd-intel8x0; modprobe snd-intel8x0 removes the whine and makes the sound card work properly once KDE is booted. Very strange! Even further, this only seems to happen for a user with a pre-exsiting .kde directory. A fresh user with a Fedora-created .kde does not encounter this problem. Given the relative obscurity of it I think it would be fair to just mark this as WONTFIX, though this is a fairly common upgrade path and sound chip so it might be worth further investigation? I could tinker with the KDE startup and/or post an archive of the .kde dir that is causing the problem if anyone is interested. In the meantime I am advising the user to delete her .kde dir and adjust all the configuration settings back by hand.
If you fire up a mixer and turn down the various recording things it should go away. Can you let me know if that helps ?
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.
