NEW RX570 NO AUDIO OVER HDMI

Just got an RX570 for my 2400G and after installing, my monitor speakers no longer output sound. The only way i can get sound is by plugging in headphones. When i removed the gpu and ran off the vega 11, Sound played fine via the monitor speakers. With the gpu, when i go into device manager i notice that AMD HD is missing from sound tab where as it is present when running from vega 11. Ive tried to reset my pc , used ddu and installed drivers again and nothing is working....

Found the reason! It does not depend on the drivers in any way. I have an RX580, a problem with audio interrupts (solved, it seems). Everything was done. As a result, I noticed that in idle time the video card switches to PCE-e 16x 1.1 mode, with a small load it returns to 16x 3.0 and at this moment an interruption occurs. Solution: I increased the minimum frequency from 300MHz to 310Mhz. Now 1.1 does not switch and the problems are gone!

Sorry for the grammar, online translator

Clarification after tests. You can put 300, but the minimum state is to choose the second
