Just to clear the air a bit....   and make sure that I am not misleading
anyone with false impressions.... (often the case)...

I took my Toshiba nb305 and wiped the Ubuntu partition and reinstalled
lucid 10.04 from a USB key as previously.  I tried the sound by turning
on the system sound (Ubuntu), opening a terminal window and holding down
the back arrow at the CLI prompt.  The sound is fine.

Now I
1) sudo gedit /etc/default/grub
2) Change: GRUB_CMDLINE_LINUX_DEFAULT="splash nohz=off highres=off"
3) save and sudo update-grub

I have to do this to get the machine to boot quickly and to suspend/re-
awaken when I close/open the lid.  I cannot change the SATA BIOS
parameter to compatibility from AHCI as I am dual booting with Windows 7
and using compatibility instead of AHCI craps up my Windows partition.

But here is the catch 22.  After putting nohz=off and highres=off on the
GRUB command line, the sound no longer works!!!!  It appears to have had
nothing to do with Twinkle installation (see messages above).  If I
remove the highres=off from the command line, the sound becomes
normal.... but then I can't recover from suspend.

So....   What do the nohz=off and highres=off parameters do?  Is
highres=off turning off high resolution timers?  Why does the sound get
restored to normal when I shut off pulseaudio?  Can I compile pulseaudio
in a way such that it is not susceptible to these high resolution timer
issues?
