internal mic not working with hdaudio intel

[marco]

Hi! I switched to oss few years ago while my sound card wasn't supported by alsa, or maybe because with alsa only one program at time can use the card, I don't remember. Now I need to install skype which does not support oss anymore but I don't want to install alsa or any sound daemon because I'm feeling good with oss. I thought to use skype from virtualbox but the internal microphone does not work. I know I did it working but then I disabled it because it was not useful and sometime it caused some troubles. Now I cannot make it work again so any hints are really welcome. I'm planning to use skype from a second computer intead of replace oss with something else.

I know intel hdaudio is a wild beast, here some infos. Thanks

vmix0-channels <Stereo|Multich> (currently Stereo)
vmix0-src <High|OFF> (currently High)
  Sample rate conversion quality used by the virtual mixer.
 
  Virtual mixer uses internally a fixed sampling rate that can be set
  using the 'vmixctl rate' command (usually 48 kHz by default). Applications
  that want to use different rates will be handled by performing automatic
  sample rate conversions (SRC) in software. This operation will consume
  some additional CPU time depending on the quality. The following
  alternatives are availabe:
 
  Fast:   Use fast linear interpolation algorithm (low quality).
  Low: Use slightly better linear interpolation
  Medium: Use an algorithm that provides good quality with moderate CPU load.
  High/High+/Production: Higher quality algorithms that consume more CPU resources.
  OFF: No sample rate conversions. Sample rate locked to the master rate.
 
  'Fast' will work best in most cases. Only users with high end audio
  cards and speakers should use the other settings.

This is really strange, after I putted my laptop to sleep and resumed it the microphone started working. Do you have an idea on what happened?

[cesium]

A) Does recording work in general? Try 'ossrecord - | ossplay -' to test it... [Edit: didn't see your last message when I wrote this. Hmm.. maybe all it needed was a reset of sorts? Assuming the computer is restarted, would recording still work?]
B) IIRC, VirtualBox needs a patch for recording to work with oss_hdaudio... [Edit: (see here)]
C) See here for skype instructions.

When the microphone didn't work recording didn't work too, `ossrecord - |
ossplay -` produced no sound. Now it works, with a load noise if the volumes,
input and output, are too high.

Before "the last resume" I tried several things: different oss and kernel
versions so the reboots were mandatory. Now I am a bit scared of a new reboot,
will it works again?

B) IIRC, VirtualBox needs a patch for recording to work with
oss_hdaudio... [Edit: (see
here)]

The first thing I tried after the discovery, was the skype testing call inside
virtualbox and it worked.

edit: I'm currently running windows xp inside virtualbox, not linux.

C) See
here
for skype instructions.

I knew that page and tried to configure pulse audio with oss but it isn't so
simple. The fact that skype executable is a 32bit and I am in debian 64bit
doesn't help.

Now I have a new question: will the microphone continue to work after a new reboot? Should I take care of something?

Now I need to install skype which does not support oss anymore but I don't want to install alsa or any sound daemon because I'm feeling good with oss.

Those "instructions" seem to be rather confusing.

In short: if you want to use Skype with OSS4, you may simply install skype-oss
For example:

Code: Select all

$ yaourt skype-oss
1 community/skype-oss 2.0.0.72-3 [installed]
    P2P software for high-quality voice communication (OSS-compatible version)
2 aur/bin32-skype-oss 2.0.0.72-4 (0)
    P2P software for high-quality voice communication (OSS-compatible version)
==> Enter n° of packages to be installed (ex: 1 2 3 or 1-3)
==> -------------------------------------------------------
==>

If you do not know what "bin32-skype-oss" is, you may ask for help on Ubuntu forum.
