The proprietary drivers their pros and cons. The issues you're running into are one of the well-known cons - if you want to run stable kernels, they'll be occasionally breaking, and if you run mainline kernels they'll break all the time. If you're going to run out-of-tree kernels you should almost certainly stick to longterm kernels. Usually people use the proprietary drivers for gaming, high-performance 3D graphics in general, or CUDA (AI, video encoding, etc). If you aren't doing one of those then I suspect the linux-supplied drivers will just work and shouldn't ever break. You can run stable kernels all you want with those. -- Rich

I won't be telling you what to one way or the other about pulseaudio, but I don't expect ALSA to stop working any time soon. Just for reference, to get sound to my TV when playing video with mpv (originally a fork of mplayer, so possibly accepts most of the same parameters that would work for you in smplay), I use this parameter: --audio-device=alsa/hdmi:CARD=NVidia,DEV=0 Looking at your aplay output from the old kernel, putting this in Smplay might work: Output driver: alsa/hdmi:CARD=NVidia,DEV=1 I wonder though if it means anything that in the new aplay -l output for your TV it says, Subdevices: 0/1.
