Public bug reported:
We have several HP 635 notebooks running Lucid. We cannot update to a more
recent version of Ubuntu due to available software.
Sound does not work with these notebooks out of the box.
I was very happy to find that there's a backport of recent ALSA drivers for
Lucid:
linux-backports-modules-alsa-lucid-generic
This backports ALSA 1.0.23. With this version, there is sound on the HP
635, but it is very unstable: The driver crashes after a few seconds
when trying to record. (I.e., output seems to be working, but not
input).
I have manually compiled ALSA 1.0.25, and this driver works stable on
the HP 635 without crashing. (I have it recording for approx. 30 minutes
now). However, I'm not well versed in compiling kernel modules, and do
not know how to provide a backport package.
Could the maintainers of
linux-backports-modules-alsa-lucid-generic
provide a packport of ALSA 1.0.25 as a *.deb package for Lucid?
