As I note at the top of this post, “This entry is now wildly out of date. Try these instructions at your own risk. If I get a few moments, I will revise these instructions in the future.”

I haven’t yet updated these instructions; I’ve been busy and just haven’t sunk the time into sorting out the sound issues on my laptop.

If I have any updates for you, you’ll see them here. Until then, you’re best downloading your code directly from ALSA… I assume by now Tobin has merged most of these changes.

As you see, I can download the rc-3 patch but not the rc4 patch. Should I try to continue with the older number patch and the new rc4 driver?

My soundcard is an Conexant HD audio and it already works well, but the mic and headphone jacks don’t work so I can’t use my headset for skype in linux. I am trying to get this all working, and have gotten to the point that I need some help and direction from someone more knowledgeable.

Thanks, and looking forward to your reply.

I’ve updated this post to note that it is “wildly out of date.” I’m going to collect comments from here and send them off to Tobin, so he can have a look and see if there are any novel issues. In the meanwhile, I recommend you fetch your kernel patches direct from kernel.org.

Using the driver alsa 1.0.14rc3 + conexant-latest-rc3.patch i have the same problem of

( dmesg after modprobe snd-hda-intel :

Compiling the latest alsa driver ( version 1.0.14 ) the headphone and the spdif work but the microfone (internal or external) still not working

I guess it is the wrong driver, isnt’t it ?

I also get the problem that ‘AyyOhh’ has,

daan@daan-laptop:/$ sudo modprobe snd-hda-intel

Any suggestions?

I updated the instructions — Wordpress had formatted double-dash as a single, long endash (”–”), which isn’t right for command-line.

Of course, don’t know if at this point, these instructions are out of date (I posted these about 2 months ago).

configure: error: invalid variable name: –with-debug I know I didn’t type it wrong I copy pasted any hel would be great

I followed these directions, and it didn’t work. Is this supposed to work for Conexant CX20551 (Waikiki) codecs _only_, or also for Conexant CX20549 (Venice)?

Anyway, while modprobe, i get these errors – (in dmesg)

snd_hda_codec: Unknown symbol snd_hda_multi_out_dig_prepare
snd_hda_intel: Unknown symbol snd_hda_bus_new
snd_hda_intel: Unknown symbol snd_hda_build_pcms

snd_hda_intel: Unknown symbol snd_hda_suspend
snd_hda_intel: Unknown symbol snd_hda_resume
snd_hda_intel: Unknown symbol snd_hda_build_controls

Which modules or kernel build options proivde these symbols ?

The problem is that I do not have a Master channel. In my case, the PCM channel partially behaves as “a master” channel since it controls the volume both with and without the headphones. However, its mute button is not working.

Moreover, my multimedia buttons control the first channel in the alsa-mixer list, which
happens to be the headphone channel, and not PCM. Until now I have not find a way
to make them control PCM instead.

However, even if manage to get them controlling PCM, the mute multimedia button will not work, since PCM-mute does not work within the alsa-mixer.

I would appreciate with you could pass this to Tobin.

Thanks for commenting on this piece. You’re right — you need to use patchlevel 1 (not 0) with that patch. I knew that but somehow copied my original mistake.

As for your explanation of PCM and PCM-2, read carefully this part of my post:

“The new patches aren’t perfect. I’m noticing some sound quality issues at high volumes, and in order to get it to work Tobin had to essentially enable two PCM channels (PCM and PCM-2), which have a very strange behavior. The first one controls the volume directly from the sound system. The second one controls the volume only between the sound system and the speakers (and thus, will have no effect on the sound when the headphones are plugged in). The master volume control effectively modulates both of these. Tobin has told me that the chipset produced by Conexant is particularly weird, which is why he had to this. I find that it’s not so bad, as long as I keep a launcher to gnome-volume-control set up so that I can control it, knowing these rules.”

I am not sure why you don’t utilize the “Master” channel in your Alsa Mixer. On my system, I’ve had success by keeping PCM and PCM-2 at about 80% volume (which results in good playback from speakers and from headphones). When I plug in my headphones, the speaker PCM channel mutes, which is what you expect. When I unplug my headphones, the speaker PCM channel unmutes. I can modulate both using my multimedia buttons since these control the Master channel. Is this not what happens for you? If so, I’ll pass this note along to Tobin so he can contact you directly.

About my previous posts: If you are reading this and had the same
problem as I, when asked about the file to be patched just type
“pci/hda/patch_conexant.c” (without the quotes).

The result is awesome! Every thing works, or almost

MIC:

- internal mic an external mic working
- internal mic is automatically disable when external one is plugged
in, and comes back to life when ext mic is unplugged.
- alsamixer used to have two switches for selecting int/ext mics, now
they are gone and the right mic always work

SOUND:

Some minor bugs here, but working:

Playback tab in alsamixer now have 4 controls:

. headphone
. pcm
. pcm-2
. Speaker

With the headphone unplugged, the sound can be controlled by
either pcm, pcm-2 or speaker. However, only pcm-2’s and speaker’s
mute-buttons work.

With headphones plugged in, the sound is controlled by both
headphone and pcm… and both mute-buttons work.

When unplugging the headphones, sound is muted. in fact,
both pcm-2 and speaker are muted. So to have sound working
again, I have to open alsamixer and un-mute pcm-2 and speaker.

Annoying: The only way to have the multimidia buttons controlling both
headphones and normal sound is to configure alsamixer applet to
control PCM. However, in this way I am no able to mute the normal
sound (remember pcm mute-button is not working without headphones).

Hope this is usefull to some one. By the way, my system is:
