Exclamation Microphone problems with nForce 570 HDA w/ALC882 (long)


I am unable to make the microphone work on my new SN27P2 SFF machine, running Xubuntu with kernel 2.6.22.1 and ALSA v1.0.14. No matter what I do, I am simply unable to get any input from the microphone! programs such as Skype simply do not detect any sound from the microphone, despite being able to get feedback from the

The kernel outputs the following when I load the v1.0.14 snd-hda-intel driver:

Code:
ACPI: PCI Interrupt Link [AAZA] enabled at IRQ 22
ACPI: PCI Interrupt 0000:00:06.1[B] -> Link [AAZA] -> GSI 22 (level, low) -> IRQ 22
PCI: Setting latency timer of device 0000:00:06.1 to 64
hda_codec: Unknown model for ALC882, trying auto-probe from BIOS...
After endless Google searches, I discovered that the current driver currently does not support the nForce 570 chipset implementation, leading to the last message from the driver. As a result, I tried every sensible option listed in ./alsa-kernel/Documentation/ALSA-Configuration.txt for the ALC882. The SN27P2 has the following jack configuration, from left to right:

Rear:
Code:
                     Front Out (Left/Right)   Center/Bass
SPDIF Out (Coax)     Line In                  Rear Out (Left/Right)
SPDIF Out (Optical)  SPDIF in (Optical)       Side Out (Left/Right)
Front:
Code:
Microphone Headphone
As a result, I figured that the 6stack-dig model option was the best one, and tried that first, with no success (all output from the kernel, ALSA programs or /proc is with this option in use). After trying all the others and STILL getting no success, I have run out of ideas. Can anyone (i.e. Gruemaster, whose previous posts on the HDA driver appear very helpful) help me with this?

Thought I heard my name mentioned somewhere.

Excellent detailed output, this helps with my preliminary investigation, which doesn't look good initially. There is currently no support under the alc882 for your system, but I am reviewing the data and will look into a preliminary patch this weekend.

In the mean time, could you run this script and post the output? It gives me a file I can download and parse more easily.

Post Another system, another chip, same problem

BUMP.

Another system I have is experiencing similar symptoms to the above - the system is based on the Asus M2N32-SLI Deluxe motherboard with the nForce 590 chipset. This motherboard uses an Analog Devices AD1988 on its HDA bus, and has the exact same problem as the ALC882 in the SN27P2: absolutely no microphone input whatsoever.

http://pastebin.ca/663668 is the output of the alsa-info.sh script for the M2N32-SLI system (with the 6stack-dig kernel module option in use). Its jack configuration is laid out as follows:

Code:
                                                Center/Bass               Line In
                                                Rear Out (Left/Right)     Front Out (Left/Right)
SPDIF Out (Coax)     SPDIF Out (Optical)        Side Out (Left/Right)     Microphone
Even though this motherboard has a different chip, is the underlying issue the same?

In looking at the Asus pastebin file, it looks like the microphone mixer inputs (Node 0x26) are muted. In the Shuttle output, it looks like the mic is not muted, but the capture volume is at 0.

Use alsamixer to check your mixer settings. <M> mutes, and <SPACE> selects capture device.

I ran alsamixer on the Asus machine, but I don't see anything wrong. Could you be more specific about what I need to check in alsamixer?

I really don't know what to tell you. I have no real way of telling you which control manages what. Some of the controls are defined individually by a driver function, some are auto generated based on the sound device.

What I can tell you is that for the Shuttle and "model=6stak-dig", your Mic should be on Node 0x18 and the Front Mic should be on Node 0x19. Look at /proc/asound/card0/codec#0 file as you adjust the controls. The values of Amp-In and Amp-Out correspond with the volume and mute functions. If (value & 0x80) then the node is muted (ex 0x94). You can kind of follow the chain to see where these pins end up at by looking at the connections listing. For example, Node 0x18 (Mic) is connected to Node 0x22 (Audio Mixer), which is connected to Node 0x09 (Audio Input). Both the mixer and the input are muted (Amp In Vals {0x80 0x80]).

Now, it is possible that you don't have controls to unmute them, but that is rare. If you could put a snapshot of alsamiser in both playback & capture modes (use <tab> to switch modes) up on patebin.ca, that would be helpful. I may have to hack a test patch to add some more controls until we get this right.

Post Partial success with position_fix

Thanks for your help with the Asus machine; after using alsamixer, I found the control that was still muted and managed to unmute it. My microphone now works through both the motherboard-mounted jacks and an HD-Audio breakout box that came with a computer case that I put the motherboard in.

As for this:

After looking through the ALSA-Configuration.txt file in the Linux kernel source, we tried the kernel module option position_fix=1, and to our surprise, the rear audio jacks began to work! However, we still cannot make the microphone work anywhere despite this option.

The output from amixer with the position_fix option is:

I tried using the amixer command to manually unmute and modify the volume configuration on the microphone controls, but without any success.

If you need any output from the other ALSA command line programs, don't hesitate to ask.
