Audio beep tone from front proximity sensor changes

[Peyole]

About one in ten times when I am parking and trigger the beep from the front sensors the tone is slightly different. It doesn’t sound distorted but simply a separate audio file from the car. Every time I park in my garage the sensors are activated by a wall so there is plenty of times for the sounds to play. The issue has existed for a very long time but since it doesn’t affect the car I didn’t worry much about it. As it did it again this morning I thought I might as well ask if anyone else has noticed this, or if there is an issue I should be aware of from this symptom. The car is a 2022, currently running SYNC 4.2.5, but issue has existed since SYNC 2.XX

That happens when the audio plays from the IPC speaker instead of the stereo system. An occasional occurrence seems to be normal.

I am not familiar with what the IPC speaker is. And if it is changing the output source hardware on an occasional occurrence it seems like something impossible to troubleshoot without tearing apart the code running the sound output.
