#1 HP Pavilion 14-EC (DAG7GMB38C0) - Audio constantly cuts out on speakers

Hello
I have the this laptop with an audio problem, when playing audio over the speakers it will cut out every couple of seconds, when using headphones it will play fine. I have swapped the speakers with working ones and the issue still persists.
The audio codec is ALC3314, the board layout is very similar to the Pavilion 14-DV. Below are some measurements when audio is playing and when it is not. Thanks
Speaker connector
Audio playing
1= 2.6V (5V when audio cuts out)
2= 2.6V (5V when audio cuts out)
3= 2.6V (0V when audio cuts out)
4= 2.6V (0V when audio cuts out)
5= gnd
6= 3.3v
No audio playing
1= 5V
2= 5V
3= 0V
4= 0V
5= gnd
6= 3.3V
Diode mode
1= 0.489
2= 0.489
3= 0.515
4= 0.515
5= gnd
6= 0.531
