I have had a Mu-so Qb 1st Gen in our home for several years. It is connected to our wifi network and is used as an AirPlay speaker. Last week, the Mu-so was not listed as an available speaker in the Music app on our Mac or in any of our iOS devices. We also use it conjunction with a Mac program called Airfoil and it was also not listed there. The rest of our Airplay-compatible devices (AppleTVs and a HomePod mini) all show up in the list of available speakers.
The first thing I attempted was to unplug and replug in the Qb. After waiting a few minutes, it still did not show up as a speaker. I tried a few more times with no different results. I then did a reset by holding in the reset button for six seconds and waited until the light began to flash purple. Once I did that, I used the Naim iOS app to find the speaker. The app found the speaker and then it began the AirPlay Setup. It attempts to connect to the wireless network but after a few minutes, the AirPlay Setup window displays a message stating “An unexpected error occurred. Try again.” But trying again results in the same error message. I also tried to add the speaker directly in iOS. I can see the speaker in the Wifi section of Settings. I select the speaker and the AirPlay Setup begins and again attempts to make the connection but fails with the same error as above.
I haven’t made any recent changes to our wireless network other than a firmware update to our router. Our wireless equipment consists of a Unifi Dream Machine router that has a built-in access point and one Unifi AP-AC Pro access point to extend coverage. Unfortunately, the Qb is located in an area without Ethernet, otherwise I would connect it via hardwire.
Are there any suggestions on what else I should try or ideas as to what might be causing the issue?
Thanks in advance.
