I can't remember, are you using an RC (release candidate) version of alsa-1.0.15, or an issued version? I think alsa-1.0.15 was stable then. ... I do note that new builds are being made (on the openSUSE multimedia ftp site) of alsa-1.0.15 practically every week. I do not know what the difference is between a build 4 weeks ago, as opposed to one 3 weeks ago, as opposed to one 2 weeks ago ?? I would be curious to find out. ... are patches being added? I don't know.
Does your mic work with any audio software? If you have not tried, could you please try to get your mic to work with other software? I think this is important to determine. i.e. is this just a Skype config problem, or is it applicable to all applications that can accept a sound input?
From the above thread, I recall you have an ALC268. Support for this hardware code is still not great. I don't recall you trying any of the options in the /etc/modprobe.d/sound file. Note here:
for an ALC268 you can try:
3stack 3-stack model
toshiba Toshiba A205
acer Acer laptops
if you don't know the syntax, please advise, I for that I can help. Basically you look for a line like:
options snd-hda-intel enable=1 index=0
and you either change the line (or add a new line if not there) with:
options snd-hda-intel enable=1 index=0 model=toshiba ////this line works for me
Restart your alsa to test (reboot is easiest) and if that doesn't work, try acer, and 3-stack, restarting alsa after each test.
I also note for the Module snd-hda-intel (which I think you have) the following:
model - force the model name
position_fix - Fix DMA pointer (0 = auto, 1 = none, 2 = POSBUF, 3 = FIFO size)
probe_mask - Bitmask to probe codecs (default = -1, meaning all slots)
single_cmd - Use single immediate commands to communicate with
codecs (for debugging only)
enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
power_save - Automatic power-saving timtout (in second, 0 =
disable)
power_save_controller - Reset HD-audio controller in power-saving mode
(default = on)
So clearly in addition to adjusting the "model", you can also, for example, adjust the position_fix, probe_mask, and the enable_msi. Will any of those help? I don't know. I have read of one DV65xx user setting "position_fix=1", claiming it helped their audio. They stated nothing about their mic. Again, you need to restart your alsa after each test. I assume the syntax (in the /etc/modprobe.d/sound file) would be:
options snd-hda-intel enable=1 index=0 position_fix=1
Whether that works in combination with a "model=something" (like "model=toshiba") on the same line, or whether it is exclusive (and not in the /etc/modprobe.d/sound file at all at the same time), I don't know. If you find this out, please advise, as I would like to learn.
I also note on our sister forum, that one HPDV65xx user claims good functionality (with no mention of whether mic works) with a custom /etc/modprobe.d/sound file, that they obtained direct from the alsa web site:
I suppose you could also try that.
And finally, I am not a Skype user, nor is it a piece of software that I am interested in using. So I guess that is my way of saying you are mostly on your own here. I'll provide the little that I can to help get your mic working generically, but when it comes to getting it to work with Skype, you will need a Skype user to give you advice.
