Ok, so this is my first post to this forum so first, big thanks to all the people that work on this fantasic software. it's amazing.
so the setup:
I have
Athlon 1900xp
256MB ram
PVR-250
SBLive! 5.1
can't remember the mobo off hand if it might be relevant I'll open up the machine later and get the details
the background:
so I have been using r4v5 with great success, some minor issues but nothing I couldn't live with. Then I got myself a nice surround sound system. I'm connecting the spdif out of the sblive to the coax digital input of the surround sound.
I naively thought that would be all there was to it.
but I quickly found that playing back a dvd won't automatically pass the necessary info to my external decoder.
after much hunting and fidling, I somehow managed to mess up my nvidia settings (of all things, still don't know what I did)
but I figured, greate excuse to update to r5a10 (I know it's only alpha but it seems to have been dying to see what's new)
so the problem
got most things back up, and have made progress on the ac3 passthrough, the current situation is I get normal audio in live tv. and in dvd under mplayer with the
-ao alsa:device=hw#0.2 -av hwac3,
I get *some* audio, basically my surround sound cuts in and out, the best term I gues is 'choppy' but it's more off than on, I can only think that the SB card is not dellivering data
the video part is fine.
I've tried looking for a few hours and can't seem to hit upon anything decribing the same problems
help and suggestions greatfully recieved

What alsa version is installed on your system? I had issues with version 1.0.6 . Downgrading to 1.0.5 helped a lot. I believe 1.0.7 and 1.0.8 are fine too.
You could try and install the latest alsa-base and libasound2 packages and go from there.

thanks I'll give that a shot, I've just got the default that installs with r5a10 at the moment, and I believe that is 1.0.6

update... that worked great. first I did an apt-get install alsa-base
and alsa-utils
and found that things like alsactl reported the new version 1.0.8
but that /proc/asound/version
still reported 1.0.6 which is when I apprecaited the difference between the utilities and the actual compiled modules.
so I did an apt-get install alsa-source
uncompressed the archive, and confirmed I;d downloaded the source for 1.0.8 by looking at the version file.
did the usual ./configure
the a make
at which point it failed claimiing /lib/modules/2.6.9-chw-4/source was not a file or directory
so I went a took a look, and found source just where it was supposed to be.
however it was a sym link that pointed to /usr/src/linux-2.6.9
which didn't exist. so I removed the symlink, created a new one pointint to /usr/src/linux (obviosuly I had previously extracted the kernel sources)
ran make again
did a make install
rebooted and presto. ac3 pass through working perfectly, and as I type I'm watching the openning scene of armageddon.
I am now officially totally happy with mythtv, this software rocks.

Thanks Dan... almost worked for me. I also had to redo the symlink to /usr/linux but after that when I do make I get this:
Code: make -C /lib/modules/2.6.9-chw-4/source SUBDIRS=/usr/src/modules/alsa-driver O=/lib/modules/2.6.9-chw-4/build modules

It looks to me like /usr/src/modules/alsa-driver/include/linux/pnp.h is redefining some structs incorrectly or that its not being alowed to redefine them.

Thanks danW... This issue has been dogging me for awhile. I have a SB Live 5.1 that I wanted to use for playing ripped dvd's but could not get digital out working. I have seen many threads about older SB's not working through spdif. I was just about to give up and buy a Turtle Beach card until I saw your post.
Everything is working fine now. You should update the wiki DigitalAudioHowTo to include the SB info - it would help a lot of people (this issue is discussed quite a lot).
