I upgrade two ibex last night and found few sound problems below First, on video file(mpg,avi ..), when right click and choose >open with >mplayer. will bring up error " [AO_ALSA] Unable to find simple control 'PCM',0 ". I'm not sure what it is, maybe the config just is not right but I fix this by right click on movie window-> preference then on audio tab, select 'Enable Software Mixer'. [or you can do this by change 'softvol = "no"' to 'softvol = "yes"' in $HOME/.mplayer/gui.conf] Another sound issue is flash player on web[like youtube] not play sound. /var/log/message said pnix@pnix-a7n:_NHDT392$ tail -f /var/log/messages ...

For a long time my ubuntu box can't shutdown properly(not sure when this start to happen may be since upgrade to gusty). Shutdown progress bar will stop running, harddrive already stop spinning and hang. I guess it because my kernel option "acpi=off nolapic irqpoll" in /boot/grub/menu.lst without these option shutdown script work perfect. So, why i need that?? I just found the way to fix this from ubuntuforums. This is not new, many guy has this problem and it fixed. To solve this problem [for me] 1.add "apm=power_off" to kernel option. 2.add "apm power_off=1" to /etc/modules Reboot and try shutdown again this time it work perfect.
