Low Audio Volume/other audio problems with Lenovo 3000 C200

[TWhetter]

I'm using a Lenovo 3000 C200 model number 89224MG

lspci | grep Audio gives

00:1b:0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

The main problem is low volume from the headphone socket. The laptop speakers do not work at all. There is no mic input.

I have tried recompiling the alsa packages using the latest source (version 1.0.14rc2) Compiled using --with-cards=hda-intel --with-sequencer=yes --with-oss=yes
Also adding various module options for alsa in /etc/modprobe.d/alsa-base, model=laptop-eapd etc.
Everything compiled and installed successfully, same problems as before.

This is the same using 2.6.17-10 and 2.6.17-11

The only thing that brings it anything like normal is setting acpi=ht at boot, but this essentially disables acpi, not desirable on a laptop.
This brings the volume up and the laptop speakers work but the mic input remains silent. And then bug similar (if not the same) to alsa bug 2581 is apparent, namely laptop speakers not cutting out when headphones are plugged in.

Incidently I have tested this on Feisty and it seems the same.

This is already addressed in hg alsa-kernel. A backport is in progress.

I tried compiling the latest hg alsa-kernel (12-02-07) and the card is recognized properly but it still has the same problem of Low Volume and No Speakers. The Mic Input is working now although I wasn't able to record successfully.

The same problem is mentioned here https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2725

It seems it might be an acpi problem more than alsa at this stage.

Latest hg alsa-kernel was tested on 2.6.17-11 and also with the latest Feisty kernel. Same results.

I'm willing to debug this if anyone has some pointers.

I have the same laptop with no sound. At me even the acpi=ht does not help. The chip is Realtek ID 862. (Intel HDA compatible).
I tried: Ubuntu 6.06, 610, SUSE 0.2.
The alsamixer showes me only a single MASTER chanel.

I compiled the newest ALSA and the supported linux driver from Realtek. (Unfortunatelly the chip 862 is not found in the supported list.)
After the compilation the alsamixer showed the MASTER and PCM
chanels. But the sound does not work. (The hardware is good, because I tested it XP.)
Has anybody any idea, what to try yet?

Pay Attention!
In the Lenovo 3000 c200 the sound works with acpi=ht set at grub's menu.lst, only if the Internal Modem is set ENABLED in the setup!

There is a continuing problem here (Lenovo 3000 C200). The ALSA changes now allow the chip to be identified correctly (Realtek ID 862), but there is still no support for the machine configuration -- no speakers, extremely low headphone level. Audio is unusable here.

The boot option acpi=ht is simply not a viable workaround -- no processor clock control, no auto shutdown, no battery monitoring (the list goes on). Even the audio remains unusable -- there is no speaker mute when headphones are connected (no jack sensing?) so the configuration is still not right.

It's more than a Wishlist status, too, imho!

[TWhetter (twhwtter)]

Agreed on the Wishlist status :(

I'm not sure what to do with this bug anymore. Its status seems to have changed to fix released, but this is only half the problem. It is certainly not fixed, even in Feisty.

Does this need re-submitting to the acpi team also?

Anyone's knowledge on how best to proceed would be very much appreciated.

[Nicholas Wastell (nickwastell)]

I'm inclined to try on the ALSA bugtracker -- bug #3008 <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3008> is the same problem/hardware.

I may be naïve, but looking through other bugs with similar symptoms, I think it's a problem with I/O configuration for the Realtek chip -- perhaps the acpi thing is a red herring.

[Nicholas Wastell (nickwastell)]

Progress is being made at ALSA bugtracker, bug #2725, with Realtek support.

[TWhetter (twhwtter)]

Excellent news, cheers for the headsup.

Speakers and acpi!

como se descarga el driver

[Nicholas Wastell (nickwastell)]

In case anyone comes here looking for the solution, the stable alsa-project.org release 1.0.14 now includes the Realtek patches for this bug.
