xawtv - wintv-pvr usb2 "can't play audio stream"

user · May 17, 2009, 10:08pm

Hi all,

I tried to set up my wintv-pvr today by using the how-to on this website:

Set up Hauppauge WinTV-PVR USB2 - openSUSE

I get the error message “cant play audio stream” on the start of xawtv. I tried the troubleshooting methods outlined in the howto to correct the problem but it doesn’t work.

I have only one sound card on the system, sb audigy and it is the only device configured in yast.

In accordance with the instructions I have tried restarting alsa.

Also, lsof shows that the /dev/dsp is not open but it does exist.

Also, sound works fine otherwise.

I have also tried launching xawtv with the dspdev parameter set to /dev/dsp … this also doesn’t help.

Any help that any of you could provide would be appreciated. Assume my knowledge of systems tools is low, so if you need some information let me know how to get it.

thanks.

Hi,

you could try TV-Viewer. This is an application especially designed for TV-cards with a build in hardware mpeg encoder. Be sure to install the latest beta.

Regards
