We have a Poly Studio R30’s speaker and while mic and camera were fine, audio wouldn’t work. I gave the task to Fable 5 and went to lunch. Since it can’t hear, it recorded the room through my MacBook mic with ffmpeg while playing test tones, so it could check for itself whether any sound came out. Then it installed the Poly management app, realized the UI hides all the useful controls, cracked open the electron app bundle, reverse-engineered the private local protocol it uses to talk to the device, and wrote a Python client to send commands directly. In the device’s internal config it found the culprit: a “USB Async Audio” flag that silently kills the speaker. It flipped it, rebooted the device through a hidden command, and verified the fix with its own mic recording. Came back from lunch to working audio. This feels differently. submitted by /u/AbbreviationsBest858
