In a system that was upgraded, (new install,) from Debian 7 to 8 with a WinTV model 109, (external 1/8" audio connector on the WinTV card to Line In of the PC.):
xawtv works fine. mplayer works fine. after mplayer, xawtv is muted, (NOT via alsa/pulseaudio, the external audio connector has no signal, via an oscilloscope.) Video is fine. There is no unmute shown on alsamixer for the xawtv/Bt878. The settings for alsamixer do not change on any card during the above test. All I can figure is that mplayer set something in v4l, but I don't know how, or how to fix it. Any help would be greatly appreciated ...
