Hi All, I have an O2 Joggler with the alsa-info output file located here: http://alsa-project.org/db/?f=4012bb42964e3c87ae7ff4e0561d9ee9d3eb5e2c

The sound does not work unless I remove the following line from /etc/modprobe.d/alsa-base.conf

# Power down HDA controllers after 10 idle seconds options snd-hda-intel power_save=10 power_save_controller=N

I believe this means that the chipset is not able to wake up from power saving, and what I get is crackling sound.

What can be done so that this issue is fixed (the device works with power saving)?

The device came with a special version of Ubuntu Linux 8.04, and the source code (included Alsa) is available at http://lists.gpl-violations.org/pipermail/legal/2009-December/001755.html

Thanks!
