[Bug 627724] [NEW] 2.6.35 snd_emu10k1x rapid "fast-forward" playback

[Vanessa Ezekowitz]

Public bug reported:

Binary package hint: linux-image-2.6.35-19-generic

While testing something on one of my Lucid boxes, I installed the
Maverick 2.6.35 kernel via the PPA designated for this purpose.  The
install and general operation of the kernel seemed to go okay, except
that audio via the snd_emu10k1x driver is badly broken - to the point of
being completely unusable.  The affected machine has an old "Dell OEM"
version of the Creative Labs "SB Live" card.

All audio sources skip forward rapidly, much like you'd get when
listening to a CD and holding down the "fast forward" button.  This
happens whether I use Pulseaudio or straight ALSA (in Audacious, for
example), even when playing via a command-line app such as 'sox'.  I
have tried the linux-image-2.6.35-14-generic-pae, -19-generic-pae, and
-19-generic (non 'pae') builds, and all of them behave the same way.

Another machine I have is running the linux-image-2.6.35-19-generic-pae
package just fine, but as it does not use this driver, it is not
affected by this bug.

I was not able to successfully build and use the mainstream 2.6.36
kernel from www.kernel.org (the affected machine needs a video driver
and virtualbox modules that apparently have not yet been adapted for
that kernel).

I use only regular analog connections (no IEC958, etc).

Rebooting with the still-installed 2.6.32-24-generic Lucid kernel,
without changing any settings, restores normal audio functionality.
