Sound doesn't work on my laptop with FC3T3. 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've update to kernel 2.6.9-1.643 and I've updated alsa to 1.0.6-3. Any advice ? How do I troubleshoot this ? -- Kim Lux (Mr.) <lux@xxxxxxxxxxxxxxxxxxx>
