This has been happening for a long, long time:

Cannot hear ATC instructions and other aircraft suddenly while AI copilot still responds

Since yesterday, the ATC is totally mute. I can see all the communication messages, but the only speaking sound I hear is “my” replies.

While that thread blames AI copilot at first, the thread evolves to add that the high demand for Azure services is likely the culprit. For example, I lose ATC voice and text whenever I have an ATC tower on COM1 and ATC ground on COM2 and the audio is a mix of both COMs at the same time.

ATC has the tendency to go silent, usually triggered by a frequency handoff and the pilot voice speaking controller script for other traffic on frequency once the copilot switches frequency.

This flaw is consistent with the idea that Azure is trying to manage 2 different COM frequencies simultaneously.
