I found several ways to get video but was missing audio then finally found a way to get both with MPlayer using the following command:

MPlayer TV with video and sound worked for a while but, as with all Beta releases, the updates were coming hot and heavy and now I'm right back where I started with video and no audio. Now when I run that command, I get the following error messages regarding audio:

I'm not tied to MPlayer so TvTime should work OK but the base Ubuntu package has no sound and I cannot get the source to compile on my system. I'm open to any/all suggestions and am willing to try any other software packages. Thanks in advance.

Hello Paul,

Is this the 800e or the 801e version of the Pinnacle PCTV HD Pro?

You're using http://linuxtv.org/hg/v4l-dvb, right?

If so, do a fresh checkout and rebuild.

Unbuntu ships its own version of em28xx, and when they update the
modules it can cause the to get out of sync with the sources you
compiled.  Doing a fresh checkout ensures that you're building against
the right version of the linux kernel headers.

Cheers,

Devin
