Fixing No Sound Issues on a 2009 MacBook Pro Running Kubuntu

It sounds like you've got the right idea! The output from `lspci | grep -i audio` showing Nvidia MCP79 HD audio and `lsmod | grep snd` listing `snd_hda_intel` is promising. If you still aren't hearing anything, try running `pactl info` and check if PipeWire is correctly set up. Also, ensure your output device is selected correctly in the audio settings.

Hey there! If your Nvidia audio chip is detected, that's a good start. You might want to check your kernel log using the `dmesg` command to look for any related errors. Also, check if you have the audio correctly loaded with some commands like `lspci | grep -i audio`, `lsmod | grep snd`, and ensure that ALSA isn't muted by checking `alsamixer`. Running a speaker test with `speaker-test -t wav -c 2` can help confirm if sound is working at all. Just remember, KDE doesn't play the boot chime by default.
