Howdy, I found a new version of the nvidia-drivers. I figured it might work with the new 6.0 kernel so I tested it. Sure enough, it compiled and installed. So, new kernel, new nvidia-driver. Keep that in mind. When I booted into the new kernel using the new nvidia drivers, sound worked everywhere except on my TV which is connected by HDMI cable. The TV works with old kernel and new drivers. The new kernel seems to be what is breaking my TV sound. I think the nvidia drivers can be ruled out at this point but one never knows.
My usual setup. I use ALSA for my sound, built into the kernel. I don't use pulse, pulseaudio or whatever for my sound. I use Smplayer to play videos on my TV which I refer to as screen 2. Some places refer to it as screen one, count starting from 0 instead of 1. So, to avoid confusion, TV screen means HDMI port used for TV. Main screen, 1 in most places, means monitor that I look at for everything other than watching TV. It is connected with a DB15HD port. I have Smplayer set to display on TV screen unless I manually drag it over to main screen to adjust something. To get sound to go to the TV screen, I set this in Smplay preferences for audio where it says Output driver: alsa:device=hw=1.7 Until now, that has always worked and that is several years and even a few kernel upgrades. Sound for Smplayer goes to TV screen but all other sound goes to the main speakers through the little jack and a amp I have hooked to it. This is some info, I'm getting same info for both kernels.

I noticed something different between the two. In old kernel, it shows 'card 1: NVidia [HDA NVidia], device 7: HDMI 1 *[LG TV ]*' which is my TV. However, under the new kernel, it does not show that. It still shows device 7 but it seems to not connect to my TV or list it. Keep in mind, the picture is on the TV. Just no sound. I went into make menuconfig and looked for some option that might affect this but if it is there, I couldn't find it. Maybe it isn't obvious. Maybe it is some hidden thing that only shows up when something unrelated is enabled. Since the new drivers work with the old kernel, I'd think that rules the nvidia drivers out. I'm thinking this is a kernel config problem but google isn't helping. Should I bite the bullet and start using that pulse, pulseaudio or whatever thing? Is the old ALSA way just getting to outdated? When I googled, it was not a lot of hits regarding alsa. The pulse thing did have hits but couldn't figure out how to apply its info to this. Thoughts? Options? Need more info? Dale :-) :-)
