Been battling this issue every night for the last month... the suggested
fix of 'iecset audio true' worked "intermittedly" - when it didn't I was
forced to create yet another install of Ubuntu Jaunty.

Discovered something VERY interesting that may save other pple some time - 
curious to know other pples opinion as I am relatively new to using SPDIF audio.
 
this is what I did
1) Upgraded the latest kernel to 2.6.31-020631, as I found SPDIF less prone to 
requiring the iecset audio true command (I suspect the issue is with the Linux 
Kernel more so then ALSA).
2) Upgraded ALSA to .21 
3) Once I got mythtv working happily using SPDIF audio from the local hard 
drive I quickly made my computer a diskless install (copied all operating 
system files onto a NFS mount (PXE image) onto my home server).  The diskless 
install worked beautifully so I disconnected my local hard drive and decided to 
use this as a backup for when SPDIF would cease working again. 
4) Low and behold SPDIF stopped working 2 days later (despite my attempts at 
using iecset audio true).  Luckily (I thought) I had a fully tested working 
backup on the local hard drive... so I reconfigured the bios to boot from the 
local hard drive install, expecting things to work straight away.  The computer 
started up as expected BUT a MASSIVE WTF => SPDIF audio STILL DID NOT WORK => 
from my prestine backup.
5) In my frustration, I turned my stereo amplifier off and the computer off for 
1 hr and tried again later => Whola => SPDIF audio returned.

Will continue testing.. but I'm completely confused by this.  Any
thoughts??

BTW: I'm running a single core Zotac Ion motherboard (NVidia ION
chipset) and the latest trunk version of mythTV.
