Hi,
I have the same model of sound card and can't make it work. I saw that
this conversation has stalled so I'm going to give informations about
what I've tested.
First thing, using one of the latest alsa-driver snapshots with a
2.6.31-gentoo-r2 kernel, I got this in dmesg when loading the
snd-hda-intel driver :
[ 111.287946] ACPI: PCI Interrupt Link [APC2] enabled at IRQ 17
[ 111.287968] HDA Intel 0000:03:00.0: PCI INT A -> Link[APC2] -> GSI 17

[ 112.575093] hda-intel: azx_get_response timeout, switching to polling

[ 113.583158] hda_intel: azx_get_response timeout, switching to
single_cmd mode: last cmd=0x107f0d00
And then, when I tried to play a sound a few times :
[ 167.997029] hda_codec: rates == 0 (nid=0x12, val=0x0, ovrd=0)
[ 173.053323] __ratelimit: 1 callbacks suppressed

[ 287.496934] __ratelimit: 20 callbacks suppressed
I made my tests with aplay and mplayer, they just stall and I don't get
any sound.
Today, after reading this thread I tried making it work with the 2.6.31
kernel from rc3 to rc6 (without gentoo patches), none of them worked. I
compiled them with debug and this is the output of dmesg when I load the
driver :

I tried using your patch Takashi, the driver wouldn't load until I put 1
in the address like Guillem did. But even with that sound doesn't work
no matter the probe_mask setting I use.
And a last note, I did my tests on the rc versions without rebooting,
just removing the module and modprobing it again, but I don't think it
matters.
Here's my lspci -vvnn :

[alsa-devel] [PATCH] Fix codec_dai->ops NULL pointer bug for AC97 codec dai in soc-core
by Barry Song 16 Oct '09
by Barry Song 16 Oct '09
16 Oct '09
AC97 codec DAIs don't register themselves eg.stac9766, wm9712, wm9713, wm9705.c, ad1980,
then it loses to the chance to be given a null_dai_ops in snd_soc_register_dai if they
have no ops. When functions like soc_pcm_open, soc_pcm_hw_params etc. access the ops field
in these DAIs, panic will happen.

[alsa-devel] How can i contribute a new AsoC codec driver for the CS42L51 ?
by Eduardo Tagle 16 Oct '09
by Eduardo Tagle 16 Oct '09
16 Oct '09
Just forgive me... I am new to this world of mailing-lists, so let me explain...
I have written an ASoC codec driver for the Cirrus Logic CS42L51 audio Codec. It
was just based on the publicly available datasheet from Cirrus Website. I really
would like to know how to submit it to be included in the official ASoC source tree.
I have tested it as much as possible, and seems to work reliably.
What are the steps required to follow to submit this new ASoC driver ?
Thanks in advance,
Eduardo

Following patch series mainly includes:
- support VT1718S, VT2002P, VT1812S, VT1716S, ...
- support smart 5.1
- add jack detection for VT1708
- power saving functions

Dear ALSA Developers,
The sound card of my laptop is a HDA Intel, chip Intel G45 DEVCTG
The PC beeps do not work correctly.
One problem is that the frequency of the beeps one can hear does not
correspond to the required frequency. For instane the command
beep 440
produces a beep whose frequency is not 440Hz
The second problem is that, although there is a PC beep control provided
in alsamixer, the control is not taken into account: the beep is loud no
matter how the control is set.
I think this problem has already been reported but can't find it in the
bug tracking system.
Could someone please help and tell me whether the problem can e solved
or not and, if it can, how.
Many thanks in advance for any help,
Sébastien.

[alsa-devel] [PATCH - try3] ASoC: Codec driver for Texas Instruments tlv320dac33 codec
by Peter Ujfalusi 15 Oct '09
by Peter Ujfalusi 15 Oct '09
15 Oct '09
Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo
audio DAC.
TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low
power audio playback.
The digital interface can use I2S, DSP (A or B), Right and Left
justified formats.
DAC33 has stereo analog input, which can be bypassed to the analog
outputs.
Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass'
mode (default) and nSample mode (FIFO is in use).
a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is
working synchronously as a normal codec (it needs constant stream of
data on the digital interface).
b) The nSample mode implementation uses one interrupt line from DAC33 to
the host:
Alarm threshold is set to 10ms of audio data (limit by the driver
implementation).
DAC33 will signal an interrupt, when the FIFO level goes under the
Alarm threshold.
The host will write to nSample register a value (number of stereo
samples), to tell DAC33 how many samples it should read in a burst from
the host. When the DAC33 received the number of samples, it disables the
clocks on the I2S bus. When the FIFO use again goes under the Alarm
threshold, DAC33 signals the host with an interrupt, and the process is
repeated.

Hello,
I'll hope that I got it right at this time, one thing that I'm not sure is the
hard power handling changes (SND_SOC_BIAS_OFF, and related things).
Changes since try2:
- dac33_write_locked simplified (no duplicated code with dac33_write)
- No unneeded casts
- hard power handling changed
- Interrupt handling is changed a bit (masking all interrupts from dac33 when
the state is FLUSH - the needed IRQ will be unmasked when the next stream is
starting)
- nSample controls added conditionally
- workqueue is created only, if we have valid IRQ number
- snd_soc_register_codec and snd_soc_register_dai moved as the last thing in
dac33_i2c_probe function.

[alsa-devel] HD-Audio Codec ALC888: Realtek Defined Registers and Digital Microphone
by Sebastian Konopka 15 Oct '09
by Sebastian Konopka 15 Oct '09
15 Oct '09
Hello everybody on alsa-devel,
I'm adding a new model to the patch_realtek.c file that supports all
features my alc888-codec together with the laptop hardware
offers. Everything works fine and can be used through alsa, except two
things, because I did not find any usable information on them:
1. My laptop has an built-in digital microphone, that is connected to
this codec according to the information I can get when using
windows. The ALC888 datasheet shows that there are pins for digital
microphone support. Thus I assume that they are used for the
microphone. Those pins are share their functionality with GPIO pins:
GPIO0/DMIC-CLK and GPIO1/DMIC-DATA.
Unfortunally the datasheet does not provide further information on
how to switch between GPIO and DMIC mode of those pins. Furthermore
there is no information where the digital data can be found and how
to transfer them over the HDA-Bus to the application.
Does anybody have additional information on how to use digital
microphones on realtek codecs?
2. Perhaps enabling the digital microphone is related to the so-called
"Realtek Defined Registers" that can be found on NID=0x20 as
processing coefficients. Furthermore the alc888 supports additional
features like equalizer or echo-cancellation, etc. that can be
controlled by these registers, as I suppose.
Does anybody have information how what these registers and their
contents mean? The datasheet does not provide any information.
I hope you can help me.

Hi,
I have a Creative XFi PCIe with ca0110-IBG chip. It's primary use is
audio input for streaming on a brand new Dell server with RHEL. I have
been testing latest kernel 2.6.31 through it's releases candidates and
the card stoped working on 2.6.31-rc6, so now I'm stuck at 2.6.31-rc5.
With rc5 I made a 2 weeks test and it went flawlessly.
There's another guy who referenced this issue on
http://mailman.alsa-project.org/pipermail/alsa-devel/2009-September/020876.…
and Takashi Iwai said that there is a communication error between the
codec and the controller.
Any workaround? Is there a bug created related to this issue?
I tried to "extract" the alsa-driver on 2.6.31-rc5 and install it 2.6.31
final without success. Also tried to get old snapshots from alsa-driver
and alsa-kmirror but I cannot compile them. Any place where get some
info about how to create
my output from alsa-info:

[alsa-devel] [PATCH - try2] ASoC: Codec driver for Texas Instruments tlv320dac33 codec
by Peter Ujfalusi 15 Oct '09
by Peter Ujfalusi 15 Oct '09
15 Oct '09
Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo
audio DAC.
TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low
power audio playback.
The digital interface can use I2S, DSP (A or B), Right and Left
justified formats.
DAC33 has stereo analog input, which can be bypassed to the analog
outputs.
Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass'
mode (default) and nSample mode (FIFO is in use).
a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is
working synchronously as a normal codec (it needs constant stream of
data on the digital interface).
b) The nSample mode implementation uses one interrupt line from DAC33 to
the host:
Alarm threshold is set to 10ms of audio data (limit by the driver
implementation).
DAC33 will signal an interrupt, when the FIFO level goes under the
Alarm threshold.
The host will write to nSample register a value (number of stereo
samples), to tell DAC33 how many samples it should read in a burst from
the host. When the DAC33 received the number of samples, it disables the
clocks on the I2S bus. When the FIFO use again goes under the Alarm
threshold, DAC33 signals the host with an interrupt, and the process is
repeated.

I might have missed something, but in short:
- Handling of mutex is reworked, so it is not taken for all I2C accesses, but
still protects the chip_power variable.
- nsample_switch handling changed
- IRQ handling reworked
- Handling of the hard and soft power states are cleaner
- definitions are namespeced
- Some generic cleanups
