Hi,
I am going to build a Linux DVR using the pcHDTV 3000 and a couple of Happauge PVR-150's. I'm still waiting for some of the equipment so I haven't started building it yet (I have the pcHDTV3000, the an ASUS p4s800d-x w/ p4 2.8, 1 gig of ram with a FX5700 and am waiting for the VGA->Component converter and the PVR-150's). I plan on using Fedora Core 5 with MythTV as I am familar with RH 9 and FC1.

So I have read the various instruction manuals out there for setting up and what not, but I am still a bit confused about sound.

For the hd3000 card I plan to hook it up to an antenea to pick up over the air HD content. I would like to get the 5.1 sound, do I need to connect the audio out of the hd3000 to my sound card? Can I pick up 5.1 sound this way? Some thigns I have read imply I do not need to do this.

I was planning to use the built in S/PDIF on the motherboard, would you suggest that or should I get a dedicated sound card (sound blaster)?

Thanks!

I'm currently using FC5 and MythTV. I am not getting a smooth HD picture, and the video quits after 2 or 3 hours.

The last good working system that I had was about 6 months ago, with FC4 and nVidia driver 7676. Then I did a bonehead thing and upgraded my system. The 7676 driver would not compile on the newer kernel.

I saw a recent post here that describes how to get the 7676 to compile on a newer kernel, but I havn't tried it yet.

For S/PDIF, the setting in MythTV is found here:
Utilities/Setup --> Setup --> (3rd screen) Enable AC3 to SPDIF Pass Through

The audio out of the hd3000 is only used for analog stations.
If you are only using the hd3000 for digital stations (either
SD or HD) you do not need to use the hd3000's audio out.

For a digital station, the audio is digital as well as the video,
and is read from the hd3000 together with the video using the
PCI bus.

I just put together a system with the HD3000 and MythTV. I am having a whole host of problems, but the one I would like to address here is sound. I finally got everything working by NOT setting it up as a DVB card, but as a straight analog card, so as you can imagine, I only receive analog stations. That's fine for now. However, I don't get any audio at all unless I connect the Audio Out port on the HD3000 to the line in on my sound card. This is suboptimal, as there is a wire hanging around on the back of the system, but I can live with it. Unfortunately, the sound track is about 1-2 seconds ahead of the video playback.

Help, please?

Does the HD3000 support btaudio? Am I using the right drivers? How do I know what the right drivers/kernel-modules are, as there are about 18 or so which have to do with the card?

Thanks.

Why is everyone alergic to wires these days?
I wish that little patch cable was the biggest problem in my life!

Might be a problem with Myth? I use mencoder to grab NTSC and
the sound is usually synced okay.

/sbin/modprobe cx88-dvb

works for me, for both analog and digital. That's just for
the HD-3000 card, not the sound card. For digital, I
use azap to tune the channel, and dd the data from
/dev/dvb/adapter0/dvr0.

I can't help you with Myth.
