Currently I cannot reliably duplicate this - I reoccurs, but I cannot predict when (usually when 3 tuners are in use, but not always). Does anyone know how I can force the tinny audio, so that I can latter confirm it's fixed?

Thanks,
Craig

I would recommend upgrading to a 2.6.18 or 2.6.19 kernel and try again. There have been improvements to the samsung tuner support starting with 2.6.18. If that doesn't make any difference then I suggest testing under Windows. It might be a hardware problem.

I have upgraded to Ivtv 7.3 and still have trouble with tinny
audio. I have a pvr-500 and would really like some help!
As far as I know the last tinny audio problems were fixed. Can you
post the IVTV INIT messages from the kernel log?
