Once again I am defeated by alsa, or debain, or somthing .... This is my fresh Debian install. Anyhew I have a mainboard like this : # dmidecode 2.9 SMBIOS 2.4 present. 75 structures occupying 2170 bytes. Table at 0x000F0000. Handle 0x0000, DMI type 0, 24 bytes BIOS Information Vendor: Phoenix Technologies, LTD Version: ASUS CROSSHAIR ACPI BIOS Revision 1103 Release Date: 03/19/2008 Lots of loaded modules like this : snd_hda_codec_analog 45530 1 snd_usb_audio 50670 0 snd_usb_lib 11192 1 snd_usb_audio snd_seq_midi 3576 0 snd_seq_midi_event 3684 1 snd_seq_midi snd_hda_intel 16823 2 snd_rawmidi 12513 2 snd_usb_lib,snd_seq_midi snd_hda_codec 46062 2 snd_hda_codec_analog,snd_hda_intel snd_pcm 47226 4 saa7134_alsa,snd_usb_audio,snd_hda_intel,snd_hda_codec snd_hwdep 4054 2 snd_usb_audio,snd_hda_codec snd_seq 35463 2 snd_seq_midi,snd_seq_midi_event snd_timer 12270 2 snd_pcm,snd_seq snd_seq_device 3673 3 snd_seq_midi,snd_rawmidi,snd_seq snd 34423 15 saa7134_alsa,snd_hda_codec_analog,snd_usb_audio,snd_hda_intel,snd_rawmidi,snd_hda_codec,snd_pcm,snd_hwdep,snd_seq,snd_timer,snd_seq_device soundcore 3450 1 snd snd_page_alloc 5045 2 snd_hda_intel,snd_pcm usbcore 99426 6 snd_usb_audio,snd_usb_lib,uvcvideo,ohci_hcd,ehci_hcd My microphone doesn't work, two entries "Microphone" and "Mic Boost" appear in the mixer but as "Playback" devices ! ? Anyone any ideas what I try next, wasted 3 hours on this so far, this is what I have tried so far in /etc/modprobe.d/alsa-base.conf # JA #https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture options snd-hda-intel model=auto #options snd-hda-intel model=asus-mode4 #options snd-hda-intel model=basic #options snd-hda-intel model=hp #options snd-hda-intel model=asus #options snd-hda-intel model=dell-m6-dmic # Crashes machine ! msi=1 # options snd-hda-intel enable_msi=1 Yes my microphone does actually work, yes I have tested it, yes it does work in another O/S and in my older copy of fedora. I also have a mixer channel center I don't want and have lost the stereo ouput I used to drive the headphones with but this is less of a problem than the missing mic :-( Thanks, Jon ------------------------------------------------------------------------------ Everyone hates slow websites.
