No sound/artsd goes wild in fresh FC3rc3
Last modified: 2015-01-04 17:11:20 EST
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041020 Firefox/0.10.1 Description of problem: Sound doesn't work on my laptop with FC3T3 or FC3rc3. It did with FC2. Here is the vital info: On login I get this message: Sound server informational message: Error while initializing the sound driver: device: default can't be opened for playback (Device or resource busy) The sound server will continue, using the null output device. Sometimes after login I get this message: Sound server fatal error: cpu overload, aborting In hwbrowser I find: Sound cards: Intel Corp. 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller Manufacturer: Unknown Driver: snd-intel8x0 If I run system-config-sound: The following audio device was detected: <blurb here, same as hwbrowser> When I press "Play Test Sound" the application hangs. If I run tops, I find that artsd hogs the cpu cycles like crazy. In dmesg everything looks normal as far as errors go. There doesn't appear to be a driver loaded for sound. Here is the only stuff I see that might be related to sound: ICH5: chipset revision 2 ICH5: not 100% native mode: will probe irqs later codec_read 0: semaphore is not ready for register 0x2c codec_read 0: semaphore is not ready for register 0x2c codec_read 0: semaphore is not ready for register 0x2c codec_write 0: semaphore is not ready for register 0x2 codec_write 0: semaphore is not ready for register 0x2 codec_write 0: semaphore is not ready for register 0x18 codec_write 0: semaphore is not ready for register 0x18 All other logs are clean. In /etc, I have a asound.state and an alsa dir. asound.state looks normal and only contains stuff about mixer. asound.conf is not present. in /etc/alsa, I have alsa.conf. There is nothing special in it. /sbin/lsmod Module Size Used by parport_pc 24705 1 lp 11565 0 parport 41736 2 parport_pc,lp autofs4 24005 0 i2c_dev 10433 0 i2c_core 22081 1 i2c_dev ds 16965 2 sunrpc 160421 1 ipt_REJECT 6465 1 ipt_state 1857 1 ip_conntrack 40693 1 ipt_state iptable_filter 2753 1 ip_tables 16193 3 ipt_REJECT,ipt_state,iptable_filter microcode 6497 0 dm_mod 54741 0 button 6481 0 battery 8517 0 ac 4805 0 md5 4033 1 ipv6 232577 10 joydev 8705 0 ohci1394 35033 0 ieee1394 302869 1 ohci1394 yenta_socket 18753 0 pcmcia_core 59913 2 ds,yenta_socket uhci_hcd 31449 0 ehci_hcd 31557 0 hw_random 5589 0 snd_intel8x0m 18185 0 snd_intel8x0 34829 3 snd_ac97_codec 64401 2 snd_intel8x0m,snd_intel8x0 snd_pcm_oss 47609 0 snd_mixer_oss 17217 1 snd_pcm_oss snd_pcm 97993 5 snd_intel8x0m,snd_intel8x0,snd_pcm_oss snd_timer 29765 1 snd_pcm snd_page_alloc 9673 3 snd_intel8x0m,snd_intel8x0,snd_pcm gameport 4801 1 snd_intel8x0 snd_mpu401_uart 8769 1 snd_intel8x0 snd_rawmidi 26725 1 snd_mpu401_uart snd_seq_device 8137 1 snd_rawmidi snd 54053 15 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_pcm_ oss,snd_mixer_oss,snd_pcm,snd_timer,snd_mpu401_uar t,snd_rawmidi,snd_seq_device soundcore 9889 1 snd ndiswrapper 114744 0 8139too 26305 0 mii 4673 1 8139too ext3 116809 2 jbd 74969 1 ext3 I figured out how to turn off aRts: Start->Control Center -> Sound and Multi.->Sound System-> General. Turn off the "Enable the Sound System" option. I also tried changing the audio device on the Hardware tab to alsa, with no effect. I'm running kernel 2.6.9-1.643 and alsa 1.0.6-3. Version-Release number of selected component (if applicable): alsa-lib-1.0.6-3 How reproducible: Always Steps to Reproduce: 1. log into KDE 2. run an application that generates a sound. kwrite on close without save, etc. 3. Run system-config-soundcard. It hangs. Actual Results: artsd goes nuts. Expected Results: system-config-soundcard shouldn't hang. Additional info:
Those codec errors appear to be from the kernel driver - assigning there.
This is still a problem as of the latest updates on Nov.5/2004 and kernel 2.6.9-1.667. The FC3 release is scheduled for Monday ? Are we not going to fix this for the release ?
Here is a work around to make sound work on my laptop: I added snd-intel8x0m to /etc/hotplug/blacklist and rebooted. I went to the KDE->ControlCenter->Sound & Multimedia-> Sound System- >Enable. Then I went to KDE->System Settings->Soundcard Detection. It detected my soundcard and it has worked ever since. artsd now consumes a reasonable amount of processor time: <1% usually.
I should add that I upgraded to FC3 final before the work around. I did this via ISO CDROMs and anaconda, ie the conventional upgrade process.
I have an acer aspire 1864 (snd-intel8x0m driver) running FC3 (kernel 2.6.10-1.741) that exhibits the same behaviour lspci outputs : Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03) Under KDE, Artsd goes wild, using 100% of available cpu (this happens at login if I have the sound system enabled) . No sound. Sound doesnt work under gnome either. Even simple methods like catting an au sound file /proc/audio hang. Same for all audio players. If artsd inst running audio players dont hang, but they dont play any sound either. dmesg shows multiple codec_read 0: semaphore is not ready for register 0x2c entries. system-config-soundcard test doesnt generate any sound and gives errors in stdout : pcm_write:1115: write error: Input/output error Always reproducible.
I have had consistent sound problems with FC1 FC2 and FC3 - sometimes it works and sometimes it does not. MY SOLUTION: I discovered a quick fix on the internet the other day - mute both microphone entries SystemSettings->SoundDetection. There are a lot of people suggesting a lot of things to help people with sound problems - if a simple mute of the microphone could help half of them - maybe that could be the default for sound i.e. microphones=muted during install? But if I was just one of a lucky few - I will be back - because I have had a lot of problems with sound.

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
This bug has been mass-closed along with all other bugs that have been in NEEDINFO state for several months. Due to the large volume of inactive bugs in bugzilla, this is the only method we have of cleaning out stale bug reports where the reporter has disappeared. If you can reproduce this bug with current FC3 updates, please reopen this bug. If you are not the reporter, you can add a comment requesting it be reopened, and someone will get to it asap. If you are not the reporter, but can reproduce this problem against FC4, please open a new bug. Thank you.
