Cannot capture streaming audio realtek ALC662 - this is a significant problem for me, I will have to use an extra soundcard and disable this onboard chip if I want anything recorded (Captured)
I use the Ubuntu>sound and video>sound recorder to try to record, not work.

Sound playback works ok
ubuntu 8.10

I have followed the actions given in
http://ubuntuforums.org/showthread.php?t=789578
but this has not changed the recording capture of streaming audio

I have spent a long time otherwise (days) also trying all combinations but conclude that the sound driver does not allow audio capture, even though audio playback works.

possible useful link, I am not able to make confident use of it:

Thanks!

Hi candtalan,

Please, if you are still having issues, test with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 325966

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

Please let us know your results.

Thanks. I have tried
apport-collect -p alsa-base 325966
however the report is:

Usage: apport-gtk <report number>
apport-gtk: error: no such option: -p
ubuntu@ubuntu:~$

For this test I am using beta1 10.04 live CD.

I confirm the problem remains as before, I use the on board integrated audio. I cannot capture audio stream with the software facilities. However if I use a hardware Y cable from line out to line in and also to speakers, I can configure to capture from line out - to - line in, but cannot do this with software.

I can capture stream if I plug in an audio card : CA 106 Soundblaster (PCI) and choose to either disable the integrated audio (via bios configure) or manually configure to use the CA 106 in pulse audio facility.

I am continuing to try to use apport-collect with more success though. thank you for your attention.

Your description is unclear: are you trying to capture from your *microphone*, or are you trying to capture what is being *played from your speakers*?

Sorry for the lack of clarity. I am trying to capture audio that ends up being played via the speakers, originating typically from internet radio etc.

As mentioned, I can do this from an added audio card, but not from the on main board facility.

Am I correct in thinking this is a software driver issue associated with the onboard chips,? Or is there a definitive way of deciding that the chipset is not hardware capable of this feature?

pactl load-module module-loopback

then use pavucontrol to record the intended sink source.

Please mark this bug fix released.

Err, sorry, I utterly misparsed that. module-loopback is *not* what you
want. It's for playing back what you record.

Search the forums for a post from komputes detailing how to do what you
want. This bug is invalid.
