An elegant hack, and I was about to suggest it when you beat me to it. There may be more audio inputs (aux?) on the mobo when you start digging around, but since you don't need that one, and if the voltages are ok (check the specs) its a cool solution. -- --JSA- ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

In fact, it looks like I'll have to use the ivtv patch for mplayer and transcode my DVDs to SVCD-quality MPEG2s. I just noticed that, although there is no place to install a CD-ROM on this PC (no opening in the front bezel -- I had to open the case to attach one and install Gentoo), there is a CD audio connector on the motherboard. I'll have to test it, but if it's a standard connector, I may be able to bring the PVR-350's audio back into the soundcard through that. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] Redirecting PVR-350 audio to soundcard for live TV / playback
After googling this problem for over a week, I'm beginning to think there is no solution. But hopefully someone here can tell me once and for all if this can be done or if it can't and I just need to let it go and move on. My setup: Compaq DeskPro EN SFF - 400MHz Celeron (Mendocino), 128MB RAM, ES1869 onboard sound WinTV PVR-350 (model 48132, rev. K268) w/ tuner LG TAPE H001F MK3 (type 47) Gentoo 2005.4, kernel 2.6.14-gentoo-r5 (gentoo-sources) IVTV 0.4.0 (latest from IVTV site) MythTV 0.18.1-r1 (emerged) My problem (and some history): The PC is a small form factor originally intended as a network appliance. Painted black, it looks sharp with my other stereo components. However, there is no audio line-in on the rear bezel nor pinned out on the motherboard. I started with a 2.4 kernel but couldn't tune in any stations; an upgrade to 2.6 seems to have fixed that (though it could have been one of the many other things I tried). Everything works, but the audio from live TV and playback comes through the PVR-350 (in MythVideo, mplayer plays video through the PVR-350 and audio through the ES1869). As noted, I can't loopback audio from the PVR-350 to the ES1869 as there is no line-in. I know that audio can be pulled directly over the PCI bus from bttv cards; I'm wondering if the same can be done with a PVR-350, and how I would set that up? I read that MythTV 0.18.1 fixes "live TV audio loss when viewing mpeg2 transport streams." That sure sounds like my problem, but maybe I've misconfigured something so that bug fix isn't implemented? Maybe Gentoo's MythTV-0.18.1-r1 is configured a certain way and I need to unmerge it and download and compile directly from the MythTV site? I have one PCI slot free so I can put another sound card in, but I find this solution distasteful as I already have a perfectly good (if incomplete) sound card on the motherboard (which took some effort to set up, too). But if I have no choice, I have no choice. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
