Ok, I don't think that is a problem. I am capturing mostly via firewire. I also have a PVR-250 for any SD programs that conflict (and HD has priority), but I haven't noticed any crackly audio.


Aggressive Soundcard Buffering:

Ok, so I'll leave both settings off. Easy enough!


Actually, you will want the Extra audio buffering turned on (it should be on unless it causes problems). And, since you have a PVR-250, you will see problems during dark scenes without it (but until you cure your current problems, the problems this fixes are lost in the noise). I was just trying to point out that these were not the causes of the problems you're describing.

So, you do need to fix your .asoundrc.


Yes, I had come to the same point, and made those changes (hw:0,4 was the only needed change to point to the digital out on this Intel board). Unfortunately, it didn't help.


Are you still using ALSA:spdif? That will not work. spdif is an alias that sends the stream directly to the digital output (on your card, hw:0,4)--which is expecting 48000Hz PCM (for PCM, that is--AC3 would also work, but you won't get that from NTSC broadcasts). You'll need to change it to ALSA:mixed-digital or ALSA:digital or uncomment the appropriate lines of the .asoundrc to set your default output and use ALSA:default. Note that if using OSS emulation, you'll need to set the default output appropriately (meaning you might as well set it).

P.S. I suppose there are four other possibilities for stutter. One, I used Jarod's guide suggestion to make mythfrontend run as root, but for some reason mythfrontend still says I need to SUID as root for smoother playback.


as root:
chmod a+s /usr/local/bin/mythfrontend

(In section "Enabling real-time scheduling of the display thread." at http://www.mythtv.org/docs/mythtv-HOWTO-5.html#ss5.4 )


On FC3, the "local" part does not apply, correct? I think what I did didn't have the "a" (only the "+s") so I'll try that when I get home.


If you're using a packaged version of MythTV, it's generally installed in /usr; whereas a compiled-from-source version is typically installed in /usr/local. Therefore, for your configuration:

chmod a+s /usr/bin/mythfrontend

Two, my video sync is still USleep, as I can't run 7174 (see previous post about "split-screen" effect) and can't get OpenGL to run on 6629 (crashes X when I run glxgears).


Shouldn't make that big of a difference (although I recommend fixing your driver installation, anyway).


I wish I knew how. I've installed 6629, 7167 and 7174 and the first does not allow any OpenGL apps to run, and the latter two both have the split screen problem. I have a GF2 card I can try, but would rather use the FX5200 as I have mostly working modelines that took forever to get right. But, if I must, I must. After building this box over nearly two years, what's a few more weeks to get another video card, right?


GF2 would probably have the same problems. It's probably because of using the wrong GL libraries (i.e. the ones in X instead of nVidia's), but that's a whole different thread... :)

Regardless, you'll want to fix your audio, anyway.


Yes. I don't know whether the AD1985 on this Intel board is a hardware or software card.

Software.  It uses the same driver as the nVidia nForce.

Considering it mentions AC'97 I would think it may be software based, which 
would mean I'd be better off just getting a new card

I wouldn't necessarily say that's true. Audio processing tends to require little effort from modern CPU's. Once you configure yours correctly, it should work fine.

(I have open PCI slots, although it would mean having three cards adjacent, 
which isn't great for airflow.  I don't really want to spend too much on a 
card.  Is the Hercules Digifire card hardware based?  Or should I bite the 
bullet and get an Audigy?

Don't know about the Hercules. The only hardware ones I have are SB cards with the Emu10K1, but I haven't bought a discrete sound card in 6 years, so...
