Sped up audio

I have installed bazzite on an old, AMD gaming PC, a Ryzen CPU (can't remember which at the moment) and a RX 580

Everything worked perfectly when I hooked it up to an old CRT, and then when I hooked it up to a newer monitor. For the CRT (Wega Trinition HD CRT) I used HDMI, and for the monitor I used an auxiliary cable. Now I have it hooked up to a 4K TV downstairs with HDMI, and the audio is sped up and high pitched, otherwise everything works perfectly. Any suggestions?
Solution
Turns out the issue was that I was outputting 2K 60Hz, too much for the GPU to handle while also feeding audio
