HVR-1800, can't get audio with tvtime

Hiya,

I'm having trouble getting my HVR-1800 tuner card to work with analog. I get video just fine, however I can't get any audio (this is using tvtime. want to ensure I can get it running with this before venturing into mythtv). Permissions are good on sound/video devices, i specified all the line mixer's. I can't quite figure out how to get this working.

Anyone have experience with this card?

Some odd observations;
-I get a /dev/video0 and a /dev/video1 (assuming 1 is the hd tuner and the other the analog), tvtime plays the video off video0 but not video1. However, when i play the /dev/video0 device in mplayer, i get nothing, however playing the /dev/video1 device does yeild audio, but no video. So i'm confused at what's going on here.

Re: HVR-1800, can't get audio with tvtime

Don't know if this will help you or not, but I had a similar situation. My card has the cx2388x chipset as well and the only way I can get audio is to "map" the audio from my tuner card to my sound card using sox:

sox -s -r 32000 -c 2 -t alsa hw:1,0 -s -r 32000 -c 2 -t alsa hw:0,0 &

Where hw:1,0 is my tuner and hw:0,0 is my sound card.

So I launch tvtime via a small shell script to kind of automate the whole thing:

#!/bin/sh
sox -s -r 32000 -c 2 -t alsa hw:1,0 -s -r 32000 -c 2 -t alsa hw:0,0 & 
tvtime
t=`pidof sox`;
kill $t;

The tvtime FAQ got me going on this btw....
http://tvtime.sourceforge.net/help.html#audioconnect

The audio/video gets out of sync at times but I haven't found a better solution for my issue at least. Adjusting the sample rates may/may not improve things if you notice this.

Hope this helps.....
