When playing XM radio from within Vista Media Center, I select XM radio from
selection screen, I log in, I see the channel lign up, I select my Xm
channel, and it says it is playing. However, there is no audio.

Everything else that used Video or Audio works correctly within Vista Media
Center and Windows Media Player. Live TV, Recorded TV, CD's DVD's, online
media all play with sound. It is only XM radio from within Media center that
does not have audio.
I don't use the application everyday but I know it did work prior to
installing SP1. I have a new rig (1 month old), and I installed SP1 about 2
weeks ago.
I have uninstalled and reinstalled my sound card drivers and well as found
an update.
I believe there is an association between the XM radio app and the Media
player that may be missing or corrupt.
Can anyone offer any help or suggestions?

I'm having the same issue. This is a clean build of Vista Ultimate & SP1, I
have an MSI motherboard with built in audio using the Vista drivers for
Realtek AC97 audio for VIA chipsets. I've tried 2 different driver versions
to no avail. All other audio functions within MCE work with no problems. I
have a paid subscription to XM radio and can use IE and visit the XM Radio
website and use their online player with no problems. I have also added the
XM Radio gadget to the sidebar outside of MCE and XM radio plays fine, so
it's something inside MCE. I can also use Live365 inside MCE and it plays no
problem. I've also removed the sound device via device manager to have Vista
find it again to no avail.

Anyone have any luck with this yet? I am having the exact same problem.
Vista Media Center sounds work great, I'm streaming audio and video from
other sources, and I can listen to XM Radio through the XMRadio.com website.
But when I log in to XM Radio on Vista Media Center, I get the guide and I
can change channels, but there is no audio.

Are others still having this problem??
