From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 Description of problem: On my Dell Latitude D610, the soundcard is deteceted, and the snd-intel8x0 driver is loaded. This should be the correct driver, but no sound is heard when "Play test sound" is clicked. RHEL 4 WS finds the sound card correctly, as does SUSE 9.3. Version-Release number of selected component (if applicable): kernel-2.6.11-1.1369_FC4 How reproducible: Always Steps to Reproduce: 1. run system-config-soundcard 2. Click "Play test sound" Actual Results: No sound is heard Expected Results: Should have heard test sound Additional info: I see this line in dmesg: snd_intel8x0: Unknown parameter `' lsmod: Module Size Used by parport_pc 28933 1 lp 13001 0 parport 40585 2 parport_pc,lp autofs4 29253 2 rfcomm 42333 0 l2cap 30661 5 rfcomm bluetooth 56133 4 rfcomm,l2cap sunrpc 167813 1 ipt_REJECT 5569 1 ipt_state 1857 2 ip_conntrack 41497 1 ipt_state iptable_filter 2881 1 ip_tables 19521 3 ipt_REJECT,ipt_state,iptable_filter reiserfs 264757 1 dm_mod 58101 0 video 15941 0 button 6609 0 battery 9413 0 ac 4805 0 md5 4033 1 ipv6 268097 8 uhci_hcd 35152 0 ehci_hcd 41037 0 snd_intel8x0m 19589 0 i2c_i801 8781 0 i2c_core 21569 1 i2c_i801 snd_intel8x0 34689 1 snd_ac97_codec 75961 2 snd_intel8x0m,snd_intel8x0 snd_seq_dummy 3653 0 snd_seq_oss 37057 0 snd_seq_midi_event 9153 1 snd_seq_oss snd_seq 62289 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 8781 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 51185 0 snd_mixer_oss 17857 1 snd_pcm_oss snd_pcm 100169 4 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_timer 33605 2 snd_seq,snd_pcm snd 57157 12 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 10913 1 snd snd_page_alloc 9669 3 snd_intel8x0m,snd_intel8x0,snd_pcm pcmcia 29025 2 yenta_socket 21449 1 rsrc_nonstatic 12737 1 yenta_socket pcmcia_core 50909 3 pcmcia,yenta_socket,rsrc_nonstatic driverloader 333360 0 tg3 108229 0 ext3 132553 2 jbd 86233 1 ext3 ata_piix 9413 4 libata 47045 1 ata_piix sd_mod 20545 5 scsi_mod 148105 2 libata,sd_mod modules.conf: alias eth0 tg3 alias scsi_hostadapter ata_piix alias snd-card-0 snd-intel8x0 options snd-card-0 index=0 options snd-intel8x0 index=0 remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0 alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd alias eth1 driverloader
After doing some research on the Web, I discovered you have to manually enable External Amplifier under Volume Control before the sound card will work. However, this only fixed the problem when the machine is undocked. On the dock, sound still does not work.
[This comment has been added as a mass update for all FC4 kernel bugs. If you have migrated this bug from an FC3 bug today, ignore this comment.] Please retest your problem with todays 2.6.12-1.1398_FC4 update. If your problem involved being unable to boot, or some hardware not being detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE* installing any kernel updates. If in doubt, you can recreate this file using.. mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak mv /etc/modprobe.conf /etc/modprobe.conf.bak kudzu Thank you.
Sound now works through the laptop speakers but not through the dock. This is how it was in FC 3.
I recommend pursuing this with the upstream ALSA folks. They are more likely to be familiar with the hardware, and may actually be able to reproduce it. Their bug tracker is at https://bugtrack.alsa-project.org Thanks for your testing.
