Can't capture audio via ALSA

[Johannes Hölzl]

Audio capture isn't enabled by default, at least when using the snd_intel8x0
module.

The OSS driver seam to work flawlessly, skype captures audio via an microphone
without problem. To capture audio wie the GNOME recorder it was needed to
activate capturing via:

   amixer sset Capture cap

It is not possible to set this via a graphical utitliy, please make this either
available by default or provide a button in the alsamixer gui.

I have similar problems with the same driver (snd_intel8x0) and integrated sound of the nforce2 chipset. The "amixer sset Capture cap" command did nothing for me and I am still unable to capture sound using ALSA though I can record using audacity and OSS.
Gnome-sound-recorder gives the following errors:

ERROR: Could not get/set settings from/on resource.
DEBUG MESSAGE: gstalsasrc.c(575): gst_alsasrc_prepare (): /record-pipeline/gconfaudiosource/bin0/alsasrc0:

Is this symptom still valid in 6.06.1?

[Johannes Hölzl (johannes-hoelzl)]

I can now capture sound without problems.

To simulate a fresh install i removed /var/lib/alsa/asound.state (while running from another system), and booted into ubuntu 6.06.1. I did need to activate recording via the microphone, but this was possible without problem in the volume settings.

Thank you for checking this again.
