Just bought a laptop Packard Bell Easynote TJ61 with an internal sound card Conexant CX20561 (Hermosa) and successfully installed Ubuntu 9.10 64-bit. Only problem was that the microphone (internal and external) was not working in all applications (soundrecorder, audacity, skype etc). Output audio (eg- Rythmbox) worked fine with ALSA and PulseAudio.
Tried a LOT of stuff, but the decisive move was to add:
options snd-hda-intel position_fix=1 model=laptop
to the file /etc/modprobe.d/alsa-base.conf and reboot.
If hope this helps ... Another thread dealing with the Conexant chip microphone is read-only otherwise I would have posted there.
