Problems with Realtek HD Audio

Problems with Realtek HD Audio

[Shingo HORISAWA]

Hi, alsa developers.

I have two problems about Realtek HD audio.

(1) Capturing stops suddenly

  When I was capturing a sound from microphone for
recording voice 
  using "arecord", it had stopped suddenly.
  After that, I couldn't capture a sound at all.
  To repair this situation, I had to restart ALSA or
system.
  
  It seems that this problem occurs when there are heavily
loads. 
  (For example, when I was using ethereal, it occured.) 


(2) Sound from embedded speaker

  When I plug a headphone into PC,
  I can hear sounds from both of headephone and embedded
speaker.
  (Normally, sounds should be heard from headphone.)
  
Are these known problem?
And if you know how to avoid them, please tell me.


FYI, my PC is TOSHIBA dynabook Satellite K10, 
and my distro is Fedora Core 6.
The audio device is ATI technologies SB450 HDA Audio.


Best regards.

Did you get any kernel message, for example, something regarding
DMA/IRQ problem?  Does playback still work even after this happens?
How about mixer volume / switch after this?

It's likely non-implemented feature.
The driver needs to turn the HP and the speaker on/off according to
the solicited events.  This was implemented for many devices but works
only on the known devices.

The standard kernel has really partial support for recent HD-audio
devices.  Try to build the latest ALSA HG version (daily snapshot
tarballs would be easier) at first:
	ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver

Check the codec chip in /proc/asound/card0/codec#* file.  See the
kernel message whether it reports as "unknown codec".  If yes, try to
pass a proper model=xxx option to snd-hda-intel module where xxx is
the one of matching model names to your codec found in
ALSA-Configuration.txt.


HTH,

Hi, Takashi.

Thanks for your response.

At first, I tried the latest ALSA HG driver, 
but both problems occured again.

In /proc/asound/card0/codec#0, 
codec was recognized as follows:

 Codec: Realtek ALC262
 Address: 0
 Vendor Id: 0x10ec0262
 Sybsystem Id: 0x11790500
 Revision Id: x100100
 Default: PCM
   .
   .
   .

So, it was recoginzed correctly, I think.

Though I couldn't find any messages when this happend, 
but I could find the following message on
/var/log/messages 
when I started capturing by "arecord" command:

   kernel: hda-intel: Invalid position buffer, using LPIB
read method instead.

As for the playback, there is not a problem.
There aren't any changes to mixer volume / switch don't
after that.


Best Regards.

Well, the codec is usually recognized, but it doesn't mean that your
hardware is really supported.  Check out the kernel log and see
whether the driver tells about "unknown model...".  Also try to build
drivers with --with-debug=detect option for making it more verbose.

Does it appear after arecord or even after aplay?

Usually, when the DMA stalls (or not started, processed, etc), the PCM
core detects timeout and warns in the kernel log, such as "capture
read error (DMA or IRQ trouble?)".

I recommend you to try various model options for ALC262.  There are
plenty of varients, but not specific for Toshiba, so far.  But it's
still worth to try.

I tried this option, but I couldn't find such messages (or
any messages) in /var/log/messages.

No, it only appeared at the start of arecord.

I also tried all model options in ALSA-configuration.txt,
but it was the same result.


But, I noticed three facts:

  a) This problem occurs when applications are started. 
     But, after restart ALSA, it doesn't occur 
     when I start the "same" application again.
     (When I start another application, it occurs...)

  b) When I run "arecord" after some applications are
started, 
     this problem doesn't occur.
     (When I started "new" application while I'm running
"arecord", it occurs.)

  c) On CD-boot linux, such as KNOPPIX, 
     this problem doesn't occur at all.


I doubted that this is a problem around memory.
So, to make sure that, I have tried to clean a page cache
after this problem occured as follows:

  (1) run "arecord"
  (2) start wireshark(ethereal)  => arecord stopped
  (3) restart ALSA
  (4) run "arecord" again => OK
  (5) start wireshark => arecord is still running
  (6) stop wireshark
  (7) clean a page cache as follows:
         # systcl -w vm.drop_caches=3 
        => arecord is still running
  (8) start wireshark again => arecord stopped!


Does this information help to resolve this problem?

Hm, but if built properly with --with-debug=detect option, the driver
must tells you a model name when you pass model=XXX option.  Make sure
that the model option is really passed.  You can see the actual value
in /sysfs/modules/snd_hda_intel/parameters/model file.

I still have no idea why wireshark interferes the sound stuff.  Maybe
both are on the same IRQ line?  You can try enable_msi=1 option to
snd-hda-intel to split the HD-Audio over MSI, just for testing.

But, anyway, there are too little information from the sound driver
itself.  Usually when something wrong occurs, the driver spits
annoying warnings.  But in your case, it doesn't produce any errors.
Puzzling...

Sorry, I could find such descriptions on /var/log/messages

when ALSA was restarted.

When I didn't specify model, it says:

  kernel: PCI: Enabling device 0000:00:14.2 (0000 -> 0002)
  kernel: ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16

  kernel: ALSA
/usr/local/src/alsa/alsa-driver-hg20070210/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:696:

  kernel: hda_codec: Unknown model for ALC262, trying
auto-probe from BIOS...
  kernel: ALSA
/usr/local/src/alsa/alsa-driver-hg20070210/pci/hda/hda_codec.c:2171:

/usr/local/src/alsa/alsa-driver-hg20070210/pci/hda/hda_codec.c:2179:

   inputs: mic=0x0, fmic=0x18, line=0x0, fline=0x0,
cd=0x0, aux=0x0

It says that "Unknown model for ALC262, trying auto-probe
from BIOS...".

And I could find the following messages 
when model is except "hp-bpc" and "hippo" on console.

   /usr/sbin/alsactl: set_control:970: failed to obtain
info for control #3 (No such file or directory)

I tried this option for all model, but it was the same
result...
And wireshark is only one of examples.
This problem also occurs on other applications, such as
konqueror, emacs, etc...

I agree.
When capturing is stopped, there are no available
informations...

The question is whether this message _always_ appears regardless what
model option you give.  If yes, the module parameter isn't passed
correctly, i.e. something wrong with your system.

So, you have only "Front Mic" as the capture source.
Is your mixer setting correct?  Attach the generated file via
"alsactl -f somefile store" together with /proc/asound/card0/codec#0
content.

It's harmless as long as you call alsactl with -F option.
Otherwise, it's a bug of init or udev script that calls alsactl.

If I specify something model, it doesn't say that.
It say so when I don't specify any model.

I think it doesn't have any problems.

And choose 'Front Mic' as the capture source.

Hi, Takashi.

As you said, 
I raised the value of "Capture Volume", 
and chose 'Front Mic' as the capture source.

But nothing changed.

I append /etc/asound.state file.
(Of cource, I loaded this file by "alsactl restore".)

My current driver is "alsa-driver-hg20070220".

Reviewing this problem again:

  - mic capture stops when other "new" application start
  - this state continues till system or ALSA are restarted
  - applications have started once are stored in page
cash, so they don't give any influence to mic capture
    (in fact, after page cache was cleared, they stop mic
capture again.)


Best regards.
