[linux-dvb] em28xx - analog tv audio on kworld 305U

	I have a KWorld DVB-T 305U on Gentoo using the v4l-dvb-hg
package (live development version of v4l&dvb-driver for Kernel 2.6)
that I updated today (03Oct08).

	The analog TV looks great but I cannot get the sound to work.
I have tried just about everything I could find searching including:
$ arecord -D hw:1 -f dat | aplay -f dat
	and
$ mplayer tv:// -tv driver=v4l2:device=/dev/video0:chanlist=us-cable:alsa:adevice=hw.1,0:amode=1:audiorate=32000:forceaudio:volume=100:immediatemode=0:norm=NTSC
	and
$ v4lctl volume mute off; v4lctl volume 31
	and
even attempting a manual cat from /dev/audio1 to /dev/audio

So what am I missing or is audio for the 305U not working yet?

Soli Deo Gloria,
Chris
