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. //Salvador 1.

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.

The second check I noticed that for some registers the volume is defined as gain (so 0 is the least audible) and for some (CS4231_MONO_CTRL, CS4231_LEFT/RIGHT_OUTPUT) is defined as attentuation (the 0 is the most audible). In two cases, the old code set volume to the loudest and mute it with mute bit, probably the opposite what was intended. It is not a crucial patch. You may drop it.

Re: [alsa-devel] developing audio with ALSA

Hi After reading the cross-compilation instruction in INSTALL file, I already successfully configured the alsa-lib-2.0.17. I also successfully made the library. Adding --prefix=xxx during configuration can set the output directory to xxx. I also modify my Makefile for application, including the search path of libasound.so.2.***. Now I can successfully make it. However, when I run my application on the target, I got the following error message: ****************************************************************************************** ./pcm: error while loading shared libraries: libasound.so.2: cannot open shared object file: No such file or directory ****************************************************************************************** I have put libasound.so.2.0.0 in /tmp of the target. I also modified /etc/ld.so.conf, adding /tmp in ld.so.conf file. However, I cannot find ldconfig on the target. Is anyone can tell me how to solve it? Should I rebuild a busybox with this command?

[alsa-devel] maestro3 & es1988: mic range too low
by ikke 18 Aug '08

18 Aug '08

Hi, I'm having mic problems with snd_maestro3 and es1988 allegro hw. The laptop is HP OmniBook Xe3. The mic is way too silent (unusable) even with 20db boost option on. I found this seems to have been really common problem, but only one came with a fix [1] to the problem, enabling one more bit to volume control. Could someone please help me apply that fix to current alsa? I tried compiling 2.6.26.2 kernel and made the first change of the patch from mail [1] attachement [2]. No change. The second part of patch I did not find anymore from the code. There are similar parts in ac97_patch.c. Any hint what should be added there? The original patched code is somewhat outdated compared to modern one... But the reasoning for the original patch sounds reasonable. The mic volume is tunable, only at the very low range. I recall the laptop came with Win98, and there was no problem then with the sound -> not a HW problem. I have never got this laptop mic working with linux, so this is not anything that broke recently. I see there is check_volume_resolution function which tries to guess some of the register ranges, but maybe it get's it wrong with this HW. I tried with external headset, the behavior is just the same. The headset is working fine with IBM T41, so not due the mic itself. Any help would be preciated, thanks, ikke [1] http://thread.gmane.org/gmane.linux.alsa.devel/2025 [2] http://cache.gmane.org//gmane/linux/alsa/devel/2025-001.bin Other posts related, with no solutions: http://article.gmane.org/gmane.linux.alsa.user/9802 http://article.gmane.org/gmane.linux.alsa.user/15260 http://article.gmane.org/gmane.linux.alsa.user/9663 http://article.gmane.org/gmane.linux.alsa.devel/27195 HW is HP Omnibook Xe3, 00:08.0 Multimedia audio controller: ESS Technology ES1988 Allegro-1 (rev 12) Ubuntu up to date hardy, with manually compiled linux-2.6.26.2. the patch: ----------------------------------- --- ac97_codec.c Fri Jun 21 16:09:15 2002 +++ /usr/src/linux/sound/pci/ac97/ac97_codec.c Sun Jun 16 21:56:00 2002 @@ -579,7 +579,7 @@ static const snd_kcontrol_new_t snd_ac97_controls_mic[3] = { AC97_SINGLE("Mic Playback Switch", AC97_MIC, 15, 1, 1), -AC97_SINGLE("Mic Playback Volume", AC97_MIC, 0, 15, 1), +AC97_SINGLE("Mic Playback Volume", AC97_MIC, 0, 31, 1), AC97_SINGLE("Mic Boost (+20dB)", AC97_MIC, 6, 1, 0) };

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?

[alsa-devel] Problem with latest alsa-info.sh patch
by Travis Place 17 Aug '08

17 Aug '08

The latest patch to allow the uploading to alsa-project.org seems to work fine, for the most part, unless you want to use the --pastebin option for the legacy upload to pastebin.ca . It seems that the uploaded data gets truncated. Not sure if this is the script, or the pastebin having problems. Ill look into it a bit more when i have time (its 5:30am here, and i need sleep). Just thought id point this out. I realise the 'default' behaviour is to use alsa-project.org for uploading, but i feel the other pastebin.ca mode should still function(I personally get people to upload there first, and then 'submit' card details to alsa-project.org/db/ afterwards. Thanks, Travis Place (wishie)

Re: [alsa-devel] latest Mac Pro (quad core) audio issues

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: sudo cat /var/log/messages | grep ALSA Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_intel.c:1810: chipset global capabilities = 0x4401 Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_intel.c:749: codec_mask = 0x1 Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Surround Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Center Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave LFE Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Side Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Headphone Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Speaker Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Mono Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Line-Out Playback Volume, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Surround Playback Switch, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Center Playback Switch, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave LFE Playback Switch, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Side Playback Switch, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Speaker Playback Switch, skipped Aug 11 07:52:10 macprolinx kernel: ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Mono Playback Switch, skipped Let me know if I should send something else. // Salvador // Northwestern University ----- Original Message ---- From: stan <ghjeold_i_mwee(a)cox.net> To: S.

How are you determining that there is no output? i.e. what program are you using, and how Try aplay -vv some.wav Try aplay -vv -Dhw:0,0 some.wav Try aplay -vv -Dplughw:0,0 some.wav Are there error messages or does it look like it is playing without sound? Are there messages in /var/log/messages regarding sound at boot or while trying to play. I don't use pulseaudio and don't know it very well, but there is more information here. http://www.pulseaudio.org Could you run a script which provides more information about your sound setup and post the link back here? The script is found at http://www.alsa-project.org/alsa-info.sh You can run the script so the results occur locally, by specifying the ---no-upload option. alsa-info.sh --no-upload You would then paste the output into your email instead of providing a link. This information will enable me to determine if your setup is OK, and look for other problems.
