just installed slack 10 and i dont get any sound. on boot, an error comes up telling me to type alsamixer and then alsactl store in terminal. so i do this and the output of alsamixer is:
No mixer elems found.
alsactl store doesnt have an output.
i am still a noob so any help is appreciated and have never dealt with sound cards in linux. i have also checked all the sound volume settings, nothing works. in volume control there are three tabs: Silicon Lab Si3036/8 rev [audio mixer (oss)], Intel 82801CA-ICH3 modem [Alsa Mixer], and Intel 82801CA-ICH3 [Alsa Mixer] respectively. only the last tab has volume controls on it. the other two are blank
could you please print the output of "lsmod", "lspci" (needs root privs.) and tell us which card your speakers/amp are plugged into.
I am thinking you cards are detected ok but the one you use for output isn't in first place (if you get my meaning) the easiest way to remedy this is to add the ones you don't need to /etc/hotplug/blacklist which forces them to NOT be loaded at boot.
edit: btw, alsactl store usually gives no output, it just writes to the file /etc/asound.state
I see you are on a laptop, the cards I recognise are:
snd-intel8x0 18924 2 # primary card (i think) - the one that is for your speakers
snd-intel8x0m 9544 4 # modem sound device
there is also:
snd-mpu401-uart 3200 0 [snd-intel8x0] # midi device (i think)
snd-ac97-codec 49500 0 [snd-intel8x0 snd-intel8x0m] # a codec thingy
As you can tell I am not an expert, but....
try adding "snd-intel8x0m" to the list of devices in /etc/hotplug/blacklist
and let us know what happens after a reboot (also how it affects the tabs in the mixer)
"Silicon Lab Si3036/8 rev [audio mixer (oss)]" is baffling me, at the moment it is the first mixer device (ie. the first tab in the mixer) and I am not sure which module to blacklist for this. Do a search on this website to find out which module to blacklist (it may not be a snd-blabla module)
ok i blacklisted snd-intel8x0m and rebooted and now the sound works thanks.
just to better understand linux what was the problem? from what i have read it seems that sound can come through the modem or the sound card. alsa can only send sound through one of these, which by default was sendng it through the modem but the speakers were looking for input from the sound card. so we had to turn the modem off in order to make alsa send output to the sound card. am i way off?
