Distorted Sound Quality

I hope no one asked this before there's only 1 page.

I managed to get the sound up and running though not as expected. I have terrible sound quality and the song playbacks sounded like a streaming from a 56kbps modem.

Anyway my lspci returned (I guess you'd want to know):

01:00.1 Audio device: NVIDIA Corporation GK107 HDMI Audio Controller (rev a1)

I don't know where to go next? Thanks in advance!

Re: Distorted Sound Quality

Make sure that the volume is set to 0dB (100%) or below, the signal will clip above that level and sound nasty.

What do these say:

lspci -knn|grep -iA2 audio
amixer

Nope, didn't boost that volume but anyway the output:

Nvidia. Through my HDMI cable from the monitor to the CPU and to my speakers.

Re: Distorted Sound Quality

To be absolutely clear:
HDMI from PC - Nvidia HDMI output - to monitor HDMI1
monitor HDMI2 to speakers?

i.e. you have 2 HDMI cables coming out of the monitor?

Does the monitor have built-in speakers?
Perhaps you have to specify in the monitor setup that you only want sound output to HDMI2 only?

Nope. 1 HDMI cable from the monitor to PC. From the PC I connected my speakers  via the audio jack.

My monitor and my PC have internal speakers. Which I think I have disabled but I will look into that again. Least I know what to do next. Thanks!
