alsa: No mixer elems found

so this is addressed a bunch of times on the board but i can't find what im doing wrong. that and its 1:30am and im tired of looking

sound was mostly working the first install of arch (then the harddrive died)  and now i get

[root@MobileEvil will]# alsamixer
No mixer elems found

i had sound working for root.. and was trying to get it usable universily. i played with both udev and devfsd permision files.. eventually i rebooted

when the computer came to, i get the no mixer elems.. error regardless of the user

i noticed on reboot it says starting devfsd
i've installed with arch 7 base 2


i have no clue what im doing -- so i might put too much in below -- sorry

Re: alsa: No mixer elems found

it looks ok to me,
try to remove hotplug from the daemons array and if that doesn't work switch to udev,


arch + gentoo + initng + python = enlisy

Re: alsa: No mixer elems found

thanks for the timely replly (as seems to be the higher standard of the archlinux board)

hotpluggin didn't seem to affect it either way
but [for anyone searching]
snd_intel8x0m  and
snd_intel8x0
are not the same thing
-- i took the m off in rc.conf (after modprobe -r 'ing it and hearing sound) and sound seems to work fine

however.. sound is working.. again after a reboot and lsmod has intel8x0m in there

i donno.. but sounds working

maybe does it matter in what order things are loaded in

Re: alsa: No mixer elems found

remove hotplug from the DAEMONS array altogether - hotplug always screws things up and I would HIGHLY recommend never using it.... ever! (I hate hotplug)

it's quite useful if you use USB devices through libusb which does not seem to detect them w/o hotplug tho.  wink

Re: alsa: No mixer elems found

udev handles USB devices just fine... actually I should rephrase my earlier post - I hate the hotplug daemon, not hotplug itself (which is a large part of udev)

Re: alsa: No mixer elems found

as above^ i don't have udev  and need my usb printer

how hard is it to go to udev/is it worth it

(no windows to boot into if things go horribly wrong... and generally i need a printer for homework)


thanks in advance

it's very easy to switch to udev and it looks like it is the future,

there is three steps to do, check this wiki,
wiki->howtos->system->udev...

hope you not screw it up,  big_smile

udev is very easy to switch to... to summarize the howto:

1) append "devfs=nomount" to your kernel boot line in lilo.conf or menu.lst
2) convert your devfs permissions and things to udev style (to much info for me to summarize here, but it's easy, just read the howto)
3) enjoy
