Hello Experts.  I have  a Fujitsu  Esprimo V6535 laptop.   I recently installed Linux Mint 9 on it  and have had sound problems from day1.   Some days the sound will work  , then  without warning it wont be working.  Sometimes it starts again after reboot,  other times not.  I have  uninstalled and re installed pulse audio  still same behaviour.  Once its working, as long as I dont shut down its fine, If i restart  or shut down  - then its random.  My sound driver  info  from aplay -l  is

following dmesg output i needed to use "modinfo snd_hda_intel"
and added some boot parameters to fix timer problems.

and a custom modprobe.d file containing
options snd_hda_intel bdl_pos_adj=128 power_save_controller=1

Bot anyway if i keep youtube movie open for a week it gives squeaks (but reopening sound device seems to cure it)

Attaching dmesg will help me to help you better.

hello , this appeared to help
sudo /sbin/alsa reload

I found that  www.jigsawplanet.com   was running java  that seemed to have something to do with the sound problem - killing the java  app and running the above  seems to bring sound back - does that make any sense?

Do you have messages about bdl_pos_adj in dmesg when java runs?
mine could be permanent fix then.

Please post dmesg to let me have a look, it might also be a problem with particular motherboard timers. (you can edit out MAC addrs and hostnames from dmesg, they are of no use)
