[alsa-devel] Very faint sound on Dell Latitude E6500
Hi everybody,
I've received a brand new Dell Latitude E6500 and found out that the sound card wasn't exactly well supported by ALSA.
Sound is barely audible (so faint that I'm not even sure if the proper sound is output or if I just get garbage), with some loud noise here and there that seem to correspond to the saturated audio data parts.
The sound card is an HDA-Intel with an IDT 92HD71B7X codec. Hardware information can be found at http://www.alsa-project.org/db/?f=30cac30e5b1ddd9c842481a830c250cc3e593b0d. A bug report including the Windows driver .ini file is available at https://bugtrack.alsa-project.org/alsa-bug/bug_view_advanced_page.php?bug_id....
When loading the snd_hda_intel driver compiled with verbose debug mode, the following messages are printed to the kernel log.

I tried forcing the model to dell-m4-1, dell-m4-2, dell-m4-3 and ref without any luck. I also tried upgrading to alsa-driver 1.0.19 and results were identical.
Could anyone help me ? I can patch and recompile the driver is required.
Best regards,
Laurent Pinchart

Please run with --no-upload and included the result in the post.
Anyway, this problem might be related with the volume-knob. Install hda-verb and try the following
hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff or hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0

Done, output included in this e-mail.
Anyway, this problem might be related with the volume-knob. Install hda-verb and try the following
hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff or hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0
Unfortunately none of those make a difference.

Hi everybody,
I've received a brand new Dell Latitude E6500 and found out that the sound card wasn't exactly well supported by ALSA.
Sound is barely audible (so faint that I'm not even sure if the proper sound is output or if I just get garbage), with some loud noise here and there that seem to correspond to the saturated audio data parts.
The sound card is an HDA-Intel with an IDT 92HD71B7X codec. Hardware information can be found at http://www.alsa-project.org/db/?f=30cac30e5b1ddd9c842481a830c250cc3e593b0 d. A
Please run with --no-upload and included the result in the post.
Done, output included in this e-mail.
Anyway, this problem might be related with the volume-knob. Install hda-verb and try the following
hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff or hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0
Unfortunately none of those make a difference.
After doing this, check /proc/asound/card0/codec* whether this node 0x28 is really changed.
Then, try the latest alsa-driver snapshot from ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
This contains more fixes since 1.0.19. It's generated from the GIT tree below: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/alsa-driver-build.git
Also, check the headphone output at first. The speaker output needs more work than the headphone in general.
You can also try to change the power-map by hda-verb /dev/snd/hwC0D0 1 0x7ec 0 This is pretty specific to IDT codecs.
Takashi
Best regards,

Hi everybody,
I've received a brand new Dell Latitude E6500 and found out that the sound card wasn't exactly well supported by ALSA.
Sound is barely audible (so faint that I'm not even sure if the proper sound is output or if I just get garbage), with some loud noise here and there that seem to correspond to the saturated audio data parts.
The sound card is an HDA-Intel with an IDT 92HD71B7X codec. Hardware information can be found at http://www.alsa-project.org/db/?f=30cac30e5b1ddd9c842481a830c250cc3e5 93b0 d. A
Please run with --no-upload and included the result in the post.
Done, output included in this e-mail.
Anyway, this problem might be related with the volume-knob. Install hda-verb and try the following
hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff or hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0
Unfortunately none of those make a difference.
After doing this, check /proc/asound/card0/codec* whether this node 0x28 is really changed.
Then, try the latest alsa-driver snapshot from
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-sna pshot.tar.gz
This contains more fixes since 1.0.19. It's generated from the GIT tree below: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/alsa-driver-build.git
I will test the snapshot this evening.
Also, check the headphone output at first. The speaker output needs more work than the headphone in general.
The headphone output works properly with the stock 2.6.28 kernel without having to mess with volume-knob. I haven't tested it with alsa-driver 1.0.19 yet.
You can also try to change the power-map by hda-verb /dev/snd/hwC0D0 1 0x7ec 0 This is pretty specific to IDT codecs.
Thanks for your help.
Best regards,
Laurent Pinchart

Yes that's right, at least as long as analog output is concerned. I haven't tested the HDMI output (there is no HDMI connector on the laptop itself, and I don't have a docking station) and the analog inputs (internal microphone and external input) yet.

Yes it does (the range is 0x00-0x7f and not 0x00-0xff).

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/alsa-driver-build.git
I've downloaded, installed and tested the latest alsa-driver snapshot. No change was visible (or rather audible) in the internal speakers behaviour.
Also, check the headphone output at first. The speaker output needs more work than the headphone in general.
As stated in my previous e-mail, headphones work properly. Only the internal speakers cause trouble.
You can also try to change the power-map by hda-verb /dev/snd/hwC0D0 1 0x7ec 0 This is pretty specific to IDT codecs.
Changing power-map with the above command doesn't seem to have any effect either.

Hi everybody,
I've received a brand new Dell Latitude E6500 and found out that the sound card wasn't exactly well supported by ALSA.
Sound is barely audible (so faint that I'm not even sure if the proper sound is output or if I just get garbage), with some loud noise here and there that seem to correspond to the saturated audio data parts.
The sound card is an HDA-Intel with an IDT 92HD71B7X codec. Hardware information can be found at http://www.alsa-project.org/db/?f=30cac30e5b1ddd9c842481a830c250cc3e5 93b0 d. A

Done, output included in this e-mail.
Anyway, this problem might be related with the volume-knob. Install hda-verb and try the following
hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff or hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0
Unfortunately none of those make a difference.
After doing this, check /proc/asound/card0/codec* whether this node 0x28 is really changed.
Yes it does (the range is 0x00-0x7f and not 0x00-0xff).
The bit 7 is to specify the direct mode. Maybe we need to select the input of the widget beforehand:
% hda-verb /dev/snd/hwC0D0 0x28 SET_CONN 1 % hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff

I'm afraid it doesn't make any difference either.
What sounds really odd to me is that I get extremely faint sound on both speakers, with some loud noise on the right speaker that seems to correspond to the T in "fronT righT" (played by speaker-test).

Did you check proc output and see any difference at all?

SET_VOLUME_KNOB changes the Volume Knob Widget's 'direct' and 'value' fields, but SET_CONN doesn't seem to have any effect.
