Hi, I installed Gentoo on my DELL XPS M1330 laptop. I found my speaker doesn't work. But I can get sound from headphone.

The laptop uses snd-hda-intel sound card module. I got this when running `lspci -v | grep -i audio`:

Code: Select all

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

It works under 2.6.23-r4 gentoo-sources kernel. And I use ALSA provided by my kernel, the first method in the article Gentoo Linux ALSA Guide.

The result of `alsaconf` program seemed all right.

I've test the hardware under Ubuntu 7.10 and both speaker and headphone work perfectly.

I think I didn't mute the speaker. Here is a screenshot of the gnome-alsamixer: http://www.cnliufeng.com/sound.png

Does anybody have any suggestions for me? Thank you.

(I apologize if I speak English in a bad grammar

)

Well, I found the output of `alsamixer` is a bit different than `gnome-alsamixer`. Here is the screenshot of the output of `alsamixer`:

By the way, in `gnome-alsamixer`, I found the PCM row controls my first headphone(There's two headphone line-out in my laptop). The Front row control the second one. Master control the whole system. No one can let the speaker speak...

See wiki regarding "modinfo". Use Google to see how other people get ALSA to work with your hardware.

Well, I'm not sure much people use a same laptop for Gentoo. Matt Manjos had wrote an article about it, http://linux.manjos.com/dell/. I've asked him about my problem by email but the problem still exists.

Hope the wiki page you gave me will help. I'll try it at once. Thank you.

See page.

Am I alone in being able to type "XPS M1330 alsa" into Google, and getting loads of hits?

How are you loading the snd-hda-intel driver ?
You are supposed to load it like this:

Code: Select all

modprobe snd_hda_intel model=5stack

Since there are so many different specifications for the intel hd audio chip, you have to specify the model. i used 5stack, and it worked for me...
Also check out the gentoo-wiki http://gentoo-wiki.com/Dell_XPS_M1330.

hopefully the mic works know again (at some time it used to work with skype for me, but since 2 weeks it doesn't, I need to plug in an external mic)

- thanks

you could try another kernel:

helium-sources: http://forums.gentoo.org/viewtopic-p-47 ... ml#4761485 (nearly pure vanilla 2.6.24-rc*)
zen-sources: http://forums.gentoo.org/viewtopic-t-64 ... t-250.html, http://repo.or.cz/w/linux-2.6/zen-sources.git, http://www.zen-sources.org/ heavily patched & a rocket

Can you explain me how you manage to get the mic working?
I have the same computer, using last kernel sources (2.6.24) and I'm unable to have the internal mic working: everything else (speaker, headphone, external mic) is working fine.
Does anyone know what I can do ? (many ubuntu posts say that the internal mic is working, but everything I found is about kernel 2.6.22 so I guess it should have been integrated in the last kernel).

Thanks

Well, its' a shameful question

I've solved my question by using ideas of upper floors on kernel 2.6.24. Thank all of you so much!

But now I get the problem is I lost my setting of sound card after reboot. Every time I reboot my laptop, I have to run "sudo alsaconf" or else I can't get any sound.

Though it's not a big problem, it sucks when I run alsaconf by hand again and again.
