Hi Peter. Interesting from viewing the lsmod output below, that both snd-hda-intel, and snd-intel8x0 are being loaded, and also very weird. You should be able to just blacklist the snd-hda-intel module in /etc/modprobe.d/blacklist, but I've seen some folks having problems blacklisting modules, as they still seem to load. I'd suggest adding a line to /etc/modprobe.d/alsa-base, as below. install snd-hda-intel /bin/true Any module loaded into /bin/true goes to nowhere land. It's loaded, but does nothing, and is effectively sent into limbo. I've no idea why both modules are being loaded, but the above is worth a try. > > dalton:~# lsmod | grep snd > snd_hda_intel 309976 0 > snd_intel8x0 31740 0 > snd_ac97_codec 91300 1 snd_intel8x0 > ac97_bus 1952 1 snd_ac97_codec > snd_seq_dummy 3780 0 > snd_usb_audio 75936 0 > snd_pcm_oss 37824 0 > snd_mixer_oss 14880 1 snd_pcm_oss > snd_seq_oss 28544 0 > snd_pcm 68228 5 > snd_hda_intel,snd_intel8x0,snd_ac97_codec,snd_usb_audio,snd_pcm_oss > snd_usb_lib 15744 1 snd_usb_audio > snd_seq_midi 8064 0 > snd_seq_midi_event 6976 2 snd_seq_oss,snd_seq_midi > snd_rawmidi 22528 2 snd_usb_lib,snd_seq_midi > snd_seq 45872 6 > snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_hwdep > 8708 1 snd_usb_audio > snd_timer 21320 2 snd_pcm,snd_seq > snd_seq_device 7564 5 > snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd > 48772 13 > snd_hda_intel,snd_intel8x0,snd_ac97_codec,snd_usb_audio,snd_pcm_oss,snd_mix >er_oss,snd_seq_oss,snd_pcm,snd_rawmidi,snd_seq,snd_hwdep,snd_timer,snd_seq_d >evice soundcore 7488 1 snd > snd_page_alloc 9992 3 snd_hda_intel,snd_intel8x0,snd_pcm > usbcore 130032 9 > asix,usbnet,snd_usb_audio,snd_usb_lib,usbhid,ehci_hcd,ohci_hcd,uhci_hcd > > dalton:~# cat /proc/asound/version > Advanced Linux Sound Architecture Driver Version 1.0.16rc2 (Thu Jan 31 > 16:40:16 2008 UTC). > > dalton:~# cat /proc/asound/cards > 0 [default ]: USB-Audio - C-Media USB Headphone Set > C-Media USB Headphone Set at usb-0000:00:1f.2-2, > full speed There is clearly some sort of conflict going on when both snd-hda-intel, snd-intel8x0 are being loaded, so that neither is detected as a sound card in /proc/asound/cards, and only your usb headphone set is detected, and set as card0 as no other cards can be found. > > dalton:~# lspci -v | "pick out sound stuff" > 00:1f.3 SMBus: Intel Corporation 82801BA/BAM SMBus Controller (rev 02) > Subsystem: IBM Device 01c6 > Flags: medium devsel, IRQ 17 > I/O ports at fe00 [size=16] > Kernel driver in use: i801_smbus > Kernel modules: i2c-i801 > > 00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 > Audio Controller (rev 02) Subsystem: IBM Device 01c6 > Flags: bus master, medium devsel, latency 0, IRQ 9 > I/O ports at f000 [size=256] > I/O ports at f400 [size=64] > Kernel modules: snd-intel8x0 > > nh> after running alsaconf, the output of. > > dalton:~# lsmod | grep snd > snd_usb_audio 75936 0 > snd_usb_lib 15744 1 snd_usb_audio > snd_hwdep 8708 1 snd_usb_audio > snd_intel8x0 31740 0 > snd_ac97_codec 91300 1 snd_intel8x0 > ac97_bus 1952 1 snd_ac97_codec > snd_pcm_oss 37824 0 > snd_mixer_oss 14880 1 snd_pcm_oss > snd_pcm 68228 4 > snd_usb_audio,snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_seq_dummy > 3780 0 > snd_seq_oss 28544 0 > snd_seq_midi 8064 0 > snd_rawmidi 22528 2 snd_usb_lib,snd_seq_midi > snd_seq_midi_event 6976 2 snd_seq_oss,snd_seq_midi > snd_seq 45872 6 > snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer > 21320 2 snd_pcm,snd_seq > snd_seq_device 7564 5 > snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd > 48772 12 > snd_usb_audio,snd_hwdep,snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_o >ss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device > soundcore 7488 1 snd > snd_page_alloc 9992 2 snd_intel8x0,snd_pcm > usbcore 130032 9 > snd_usb_audio,snd_usb_lib,asix,usbnet,usbhid,ehci_hcd,ohci_hcd,uhci_hcd > > dalton:~# cat /proc/asound/cards > 0 [I82801BAICH2 ]: ICH - Intel 82801BA-ICH2 > Intel 82801BA-ICH2 with AD1885 at irq 17 > 1 [default ]: USB-Audio - C-Media USB Headphone Set > C-Media USB Headphone Set at usb-0000:00:1f.2-2, > full speed > > ======================================================================= > > - See how it goes with my suggestion above. Nigel. Really weird though, like the modules have been smoking some dodgy stuff, and both insist on being the one for the soundcard. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
