I'm using MC28 28.0.88 64bit with Windows 10, and my Bose Portable Home Speaker, which had been working fine, now produces no sound. If I select a track and send it to the speaker and select the speaker under Playing Now, all indications are that the track is playing, but I get no sound. The time in the Player Bar increases as it plays and continues on beyond the end time of the track. My Player and Sonos Play3 speakers work fine. The problem began 3-4 days ago, and I don't think I changed anything for this speaker. I'm able to stream Spotify from my PC to it without any problems, so I know it works.
I've powered down the speaker, exited MC28, and rebooted my PC. The speaker is associated with Generic DLNA. Everything for the speaker looks good in the Bose Music app, which doesn't show much. I've run Whitebear's Media Renderer Analyzer, and the suggested and actual MC server settings are the same. It seems like information about this speaker got clobbered in MC, but I doubt it. I'd appreciate any ideas on what to do next.
