Another Laptop without Sound.

[Anthony]

Good Evening.

First off what a great distro, I am in love. I have a Gateway MT6452 Laptop, I have installed Cassandra KDE 3.0 Community Edition. Everything seems to be working fine except the sound. Oddly enough running this in Live mode off the DVD my sound worked. After I have installed this it now does not.

I have spent the last few hours here on the forums testing different hints and suggestions but I have not had any luck. Here are different outputs.

Sound Driver 3.8.1a-980796 (ALSA v1.0.14rc1 emulation code)

Any ideas would be welcomed.

Thank you very much,

I see that modem is listed as subdevice to the STAC92xx
Try to turn on the modem

[Anthony]

Please forgive my ignorance but how? A quick search here and at Google did not seem to answer me.

Sorry to sound so dumb.. "Have not had a modem in my pc now for years."

Thanks,

Anthony

in a similar post i have seen the modem and sound card are linked.
so when the modem is disabled in the bios the sound card did not work.
when the modem was enabled in the bios the sound card worked again.

well i think it was the bios but it may have been disabled in the OS.

[Anthony]

Well no difference. I tried for giggles pop'd in the live DVD again and the sound works.
Anymore ideas?

Thanks so much for the help.

I see you have you done an update.

Does the sound work when you boot to the original kernel?
at boot hit esc to see the grub boot menu, arrow down to the original kernel and hit enter.

I have a similar problem

booting in generic 15 doesn't solve it

I tried the same commands with this output

Code: Select all

ronnil@ronnil-laptop:~$ sudo asoundconf list

ronnil@ronnil-laptop:~$ aplay -I
aplay: playbackv:2295: You need to specify 1 files

My soundcard is a SoundMax AC'97 16bit, or so the specs say

My laptop does have a modem attached, but I have no idea how to switch it off (can't access any BIOS for some reason)

I am new to linux, but i must say that this sound thing seems the most difficult to start with, lots of hits but nothing remotely noob friendly

[Anthony]

Thanks for me booting the 2.6.20-15 kernel worked. I have sound again.

Ronnil, did the sound ever work? Like from the DVD Live Disk?

Thanks for the help.

Anthony

[ronnil]

Nope haven't had any sound ever... actually at start i just thought linux started up without that annoying startup sound.

I then discovered there was no sound at all, but wanted to get my USB mouse working properly first (which i got this morning thanks to Boo )

So now I'm in to getting my sound working (and xchat... but that's another topic )

[Boo]

try booting the old kernel with irqpoll as a boot option.

you could test this with the live CD first and check if the sound works with it.

or I think under sound settings try using alsa and then oss sound. one may work and the other not.

just guessing now.
