If you have a Sonos Playbar speaker, and haven’t yet updated to firmware version 7.4, you may want to hold off for a while. Users on the company’s support forums are reporting a variety of audio issues since the update, up to and including complete loss of audio on some channels …

Others are reporting clicks when changing channels, which The Verge speculates may be Dolby-related. The site spotted the reports on the company’s support forum, where it has been acknowledged by Sonos.

If you’ve already updated, and are experiencing problems, Sonos is asking owners to submit system diagnostics via the Sonos app to help it track down the cause.

We appreciate your patience while we get this sorted. We’ll let you know when we have more details to share.

If you’re looking for a more discreet alternative to the PlayBar, we reviewed the Playbase speaker, which is designed to rest underneath your TV.

For its more music-oriented speakers, Sonos is soon to face competition from Apple’s HomePod, expected to launch in December.
