please consider turning on all possible modules for external USB devices

[Alex Chiang]

Turning on usb-audio was requested by diwic too.

While you're at it, you can disable snd-hda-intel - it just causes error messages later on :-) (There is no way we can get HDMI anyway, so...)

[Jani Monoses (jani)]

This config is disabled too if we take out INTEL_HDA.

config SND_HDA_PLATFORM_NVIDIA_TEGRA
        bool "Build NVIDIA Tegra platform driver interface for HD-audio driver"
        depends on SND_HDA_PLATFORM_DRIVER
        help
          Say Y here to build NVIDIA Tegra platform driver interface for
          HD-audio driver.

So by no HDMI you mean non HD-audio driver and that is fine for now?

this should actually cover more than just usb audio, we initially left the modules off to cut down build time for the kernel. now that we dont constantly rebuild we should switch to the same options the other ubuntu kernels have enabled (for USB stuff at least)

[Jani Monoses (jani)]

Please test the kernel in the staging PPA for the USB_AUDIO fix.
We need a separate bug to cover syncing properly with mainline kernel's configuration.

I would assume so, yes
