Stan, Thank you for spending time to look at this issue. I owe you a drink, when you are in the chicago area let me know and I'll treat you to one.

Ok, so I will check with the developers an see what can be done to correct this. Thank you.

Hello Stan,

This is awesome I did find the problem it's listed in the /var/log/messages under ALSA.

1. When I bring up the "Pulse Volume Control" gui, the first tab "Playback" comes up empty, and grayed-out is "No Streams Available"
2. aplay does not produce sound, period!
3. Amrok's welcome sample does not produce sound out of the std tower speaker or the headphone jack.

I didn't notice anything strange on the output of the alsa-info.sh file, but when I checked the var/log/messages, this is what I found:

Let me know if I should send something else.

I think your problem is a misidentification of your sound chip. The model being used for your 889A appears to be incompatible, thus all the errors above. It appears that the macpro ALC885 is being selected before it gets to the choice for the ALC889A. Perhaps a developer can look into this.

!!HDA-Intel Codec information !!---------------------------

Codec: Realtek ALC889A

!!Aplay/Arecord output !!------------

APLAY

**** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC885 Analog [ALC885 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0

One shows ALC889A and the other shows ALC885. In the driver code there is a comment to the effect that the 889A is best handled as an ALC888, yet the macpro is listed under the ALC885.

I am not a developer so can't go beyond this, but it seems that there is a problem. There should be a macpro under the ALC888 as well as the 885.

Here are the model options for the two candidates

_From the code, here is the comment indicating it should be treated as an ALC888:

if (board_config < 0 || board_config >= ALC882_MODEL_LAST) { /* Pick up systems that don't supply PCI SSID */ switch (codec->subsystem_id) { case 0x106b0c00: /* Mac Pro */ board_config = ALC885_MACPRO; break; case 0x106b1000: /* iMac 24 */ board_config = ALC885_IMAC24; break; case 0x106b00a1: /* Macbook (might be wrong - PCI SSID?) */ case 0x106b2c00: /* Macbook Pro rev3 */ case 0x106b3600: /* Macbook 3.1 */ board_config = ALC885_MBP3; break; default: /* ALC889A is handled better as ALC888-compatible */ if (codec->revision_id == 0x100103) { alc_free(codec); return patch_alc883(codec); } printk(KERN_INFO "hda_codec: Unknown model for ALC882, " "trying auto-probe from BIOS...\n"); board_config = ALC882_AUTO; } }

Hello All;

I feel confused by the presence of 2 different copies of ac97_codec.c:

jutz-gnto ~ # find . -name ac97_codec.c ./alsa-driver/pci/ac97/ac97_codec.c ./alsa-kmirror/pci/ac97/ac97_codec.c

worse yet,they are not in sync:

jutz-gnto ~ # diff -w ./alsa-driver/pci/ac97/ac97_codec.c ./alsa-kmirror/pci/ac97/ac97_codec.c 1d0 < #include "adriver.h" 38c37 < #include "../../alsa-kernel/pci/ac97/ac97_id.h" ---

#include "ac97_id.h"

40c39 < #include "../../alsa-kernel/pci/ac97/ac97_patch.c" ---

#include "ac97_patch.c"

1917d1915 < #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 0) 1929d1926 < #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 14) 1931d1927 < #endif 1953,1956d1948 < #else /* <= 2.6.0 */ < #define snd_ac97_dev_register NULL < #define snd_ac97_dev_disconnect NULL < #endif

Which of these am i supposed to use? am i supposed to change both of them for some backward compatibility purpose?

tnx!

Hi,

I don't know if there is something special I should do to be able to use dmix with my new ASoC driver I made (TLV320AIC23b codec running on a AT91RM9200 board).

The problem is when I try to use dmix with aplay, it doesn't work and I got this error message:

# aplay -v -D plug:dmix /media/usb0/tada.wav aplay: main:545: audio open error: Operation not permitted #

Listing of my /dev/snd:

# ls -al /dev/snd drwxr-xr-x 2 root root 0 Jan 1 00:01 . drwxr-xr-x 7 root root 0 Jan 1 00:01 .. crw-rw---- 1 root audio 116, 0 Jan 1 00:01 controlC0 crw-rw---- 1 root audio 116, 16 Jan 1 00:01 pcmC0D0p

Notice I have a default /usr/share/alsa/alsa.conf file too. I'm running ALSA 1.0.15. Of course, it works well when I play a sound without the -D plug:dmix parameter...

# aplay /media/usb0/tada.wav at91-ssc:ssc_startup: SSC_SR=0x000004c3 armus_tlv320aic23b: pck1 started asoc: aic23b <-> at91-ssc1 info: asoc: rate mask 0x6fe asoc: min ch 1 max ch 2 asoc: min rate 8000 max rate 96000 Playing WAVE '/media/usb0/tada.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo #

I tried to find some useful documentation about dmix but mainly it says that when we have a recent version of ALSA, we don't need to configure it because it's already done?
