No sound in Ubuntu dapper. hda-intel card. Toshiba sat pro p100-187 laptop

[maladath]

So, like quite a few other people it seems, I also have trouble with sound in Ubuntu 6.06. There is no sound. I have tried numerous troubleshooters and guides, including the comprehensive sound problem solutions guide on the forum here. After I downloaded, installed and ran and tested for a few days, and nothing worked, I decided to reinstall ubuntu and have a clean install to work from. So im on scratch.

Details:I have a toshiba sat pro p100-187 laptop. Sound works perfectly in windows

Card: HDA Intel

aplay -l result:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
Subdevices: 1/1
Subdevice #0: subdevice #0


Relevant lspci -v result: 0000:00:1b.0 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

So at least it seems ubuntu finds my soundcard.

I have two cannels avaliable to view in alsamixer. Master and PCM. Master is not muted hile PCM does not have the option of being muted/unmuted. All other sound settings in ubuntu are unmuted and have sufficient volume.

I followed the stickyed guide on the forum here, I found the driver for my cards chipset on the alsa-project.org site, which would be the hda-intel one. I run: sudo modprobe snd-hda-intel. I type in my admin pass, but nothing happends... I dont get an error message, but nothing happends and there is no sound.

I tried both the following options afterwards, Getting the ALSA drivers from a fresh kernel and the alsa driver compilation step. None fixed my problem. Still no sound.

Any ideas?

I dare to invoke a little bump here.

Im a nubcake when it comes to Linux, having installed ubuntu as my first distro only a few days ago, so would really appreciate some input. Realize there are a lot of sound problem posts, but as my attempts to solve the problem using tips and guides has been to no avail so far, I guess maybe my problem might be elsewhere.

Ive been trying to solve this same problem for months now. Its not your fault, I think we might just have to wait for new alsa drivers

Same problem and details here with a Toshiba P105-S9312

kk. Thanks for the replies people. Ill watch out for new alsa drivers and make sure I post on here if I resolve the problem of course.

I have a p105 with the Intel HDA sound and it's an ALSA issue. We might have to wait for new drivers. I'm just now looking into it but I'm not sure if anyones found a fix for the low volume/quality issue.

If you don't have sound at all you'll need to edit /boot/grub/menu.lst to add acpi=off

Here are the relevant parts from mine:

## ## Start Default Options ## ## default kernel options ## default kernel options for automagic boot options ## If you want special options for specific kernels use kopt_x_y_z ## where x.y.z is kernel version. Minor versions can be omitted. ## e.g. kopt=root=/dev/hda1 ro ## kopt_2_6_8=root=/dev/hdc1 ro ## kopt_2_6_8_2_686=root=/dev/hdc2 ro # kopt=root=/dev/sda1 ro acpi=off #### DELETED STUFF ##### ## ## End Default Options ## title Ubuntu, kernel 2.6.15-26-686 root (hd0,0) kernel /boot/vmlinuz-2.6.15-26-686 root=/dev/sda1 ro quiet splash acpi=off initrd /boot/initrd.img-2.6.15-26-686 savedefault boot

You may not need it in both spots and if you have multiple kernels you may want to add it to those as well. It only gets you halfway there but low crappy sound is better than none.

Found a solution: boot with acpi=off fixes the problem for me...

The ACPI=off thing did work on my P105-S921 but it sounds low and crappy. Anyone knows if it will get better someday?

[zgornel]

Try and get a 2.4.x kernel and see if it works. It's hardly a solution but a laptop with no ACPI is ueless. Plus, the sound is crappy

Same issues here. acpi=off works - but sound is very low and crappy.
