Of course.  I thought I would first see if I could get my TV tuner
working with ALSA and then proceed to put PulseAudio back into the mix.
I am not one of those who has given up on PulseAudio.  Sound is complex
enough to have an intervening server a la Xwindows.

I will waste (spend) a rainy Sunday afternoon here trying to get mplayer
going, both in conjunction with tvtime and independently.

I am sure you must be getting tired of this issue, but ...
I have the latest kernel source code + git here and could use some
suggestions on where to start.  I have just begun to look at kernel code
so I am sure my way will be tortuous, however, I am willing to give it a
try -- reading the comments and documentation at least.

To save me some fruitless time, would you suggest I look at the 'tuner'
driver, cx23885, cx23887, cx25840 or something else?  Maybe at the
motherboard sound chips?
