if not using pulse, did you try asound and check the levels - unmute
whatever is muted and relevant for you.
On my notebook with decent intel/realtek sound card which has HDMI and PCH
in/output I disabled the HDMI as it was listed as 1st device. Now only PCH
is available and there is sound as usual.

If it is working partially look how the components are configured as
sometime they use /dev/dsp* which blocks anything else of using the audio
system. So when one application occupies the device nothing else can play.
