[mythtv-users] RH9 / PVR 350 - no sound !

[Sen Hwei Chan]

Hi everyone,

I'm a complete newbie at this but I have been following Jarod's excellent 
guide to the letter. I'm trying to setup MythTV on a Shuttle SN41G2 XPC with 
the PVR 350 and Red Hat 9.

My video input is S-VIDEO and I've connected the RCA audio cables as well to 
provide the input. I have not connected any pass through from the PVR 350 to 
the onboard sound card.

The video captures perfectly but without any audio. The audio (nvidia 
nForce2) has been setup properly using the ALSA drivers and I can play wave 
and MP3 files.

I used the following settings to configure IVTV :

/usr/lib/ivtv/test_ioctl -u 0xff
/usr/lib/ivtv/test_ioctl -p 6
/usr/lib/ivtv/test_ioctl -f width=720,height=576
/usr/lib/ivtv/test_ioctl -v input=1,output=1

I was trawling through the IVTV mailing list archives and it seemed that the 
consensus was that "input=1" was the correct setting for s-video / composite 
audio capture.

I'm guessing that the problem lies in one of two areas :

1. Wrong MSP3400.o file ?
2. Issue with the IVTV driver.

Am I using the correct MSP3400.o file ? If not, would a kind soul be able to 
email me a working version of the file ?

[root at localhost video]# modinfo msp3400
filename:    
/lib/modules/2.4.20-20_29.rh9.at/updates/drivers/media/video/msp3400.o

parm:        simple int

parm:        dolby int

Here's the info on the IVTV drivers loaded currently :

[root at localhost video]# rpm -qa kernel ivtv-kmdl-\*
ivtv-kmdl-2.4.20-20_29.rh9.at-0.12-cvs20031004_16.rh9.at
kernel-2.4.20-8
kernel-2.4.20-20_29.rh9.at
kernel-2.4.20-24.9

My module.conf looks like this :

path[toplevel]=/lib/modules/`uname -r`/updates
# default path
path[toplevel]=/lib/modules/`uname -r`
# ivtv modules setup
alias char-major-81 videodev
alias char-major-81-0 ivtv

options snd-intel8x0 index=0
# --- END: Generated by ALSACONF, do not edit. ---
# -- Keep modules from being autocleaned
add options -k snd-card-0

I've looked through /var/log/messages and /var/log/dmesg but there weren't 
any messages that looked suspicious.

Any and all help is appreciated as I'm a complete newbie with Linux !

thanks,

Chris
