Bug 125792 – usb-audio doesn't work, when CONFIG_USB_BANDWIDTH is enabled

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Elias Probst 2006-03-10 22:41:12 UTC]

Hi,
the usb-audio driver doesn't work, when CONFIG_USB_BANDWIDTH is enabled.
Have a look here for more information:
http://forums.gentoo.org/viewtopic-p-3171182.html#3171182

Please add this line to the next alsa-driver ebuild:
hasq usb-audio ${ALSA_CARDS} && CONFIG_CHECK="${CONFIG_CHECK} !CONFIG_USB_BANDWIDTH"

I'll try to find the reason for this problems, whether it's a bug in the ALSA module or because of the experimental status of CONFIG_USB_BANDWIDTH.

Thank you!

Elias P.

1.) It looks like a kernel problem:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1642 (use the guest login)

2.) Sorry, the right correction should look like this:
hasq usb-audio ${ALSA_CARDS} && CONFIG_CHECK="${CONFIG_CHECK}
!USB_BANDWIDTH"

No, this has been explained before.  The USB_BANDWIDTH stuff has nothing
to do with the usb-audio drivers working or not working.

So do not add a check for it, it's wrong.

See the discussion on the linux-usb-devel mailing list for details.
