No sound on new laptop!

**linux_tech** · January 10th, 2009

In terminal type:

Code:

gksudo gedit /etc/modprobe.d/alsa-base

Try changing or adding the following sentence: options snd-hda-intel model=3stack
to this

Code:

options snd-hda-intel model=hp

save file, exit editor
Reboot and check if your sound if working. Do not forget to check your mixer to see if (new) channels are muted

Still opened the document, which was empty, did the save, doesn't work.

Ok, the file certainly shouldn't be empty. I suspect it opened it as empty due to the process uid issue. Quite an odd error.
Is this a clean install of Kubuntu? If not what alterations have you made?
Best advice I can give and I'd bet my house on this is that if you are running a clean install, standard Kernel, not RT, then the previously mentioned edit should give you sound. It's simply a matter of letting asla.base know what generic model laptop it is in order for it to know how to output correctly.
The error your getting suggests that a process is preventing you from opening this file correctly therefore it is appearing as a blank text file hence your changes had no effect.
You can try 2 things;
1. Boot into the LiveCD and view the alsa.base file, if empty thats your problem. You may need to reconfigure ASLA in order to rectify this. If it has all expected content smply append the previous code and you should be ok. Save & reboot.
2. Reinstall, clean, and make the edit your first action. Save & reboot. You should get sound.

Let me know how you get on
