Arc cannot decode TrueHD after recent firmware upgrade

C

I have Arc +  HDFury Arcana + UHD player and it worked well for a long time.

But with recent firmware upgrade (since March upgrade I guess), I found Dolby TrudHD can no longer being decoded. (no sound at all, and in Sonos APP no audio codec)

I have reset Arc and HDFury and there was no help.

After some trial I found Dolby Digital Plus and DTS5.1 still works so that it should be no issue with my setup. The issue only happens with TrueHD audio, even for TrueHD 5.1.


Could anyone also check if there is same issue?

PS. issue is still present with April upgrade (version 16.7 build : 84163251)

Hi ​@CharlesWoo0609, welcome to the Sonos Community!

I’m sorry to hear you’re having issues with your Sonos Arc not playing True HD. The last speaker update in March was to improve Spotify Connect stability, while the latter updates were app only so this shouldn’t have effected your Home Theater. Sonos soundbars will play what they’re given, since TrueHD is a supported format, something isn’t passing it correctly to the Arc.

To narrow down where the issue lies, please try playing TrueHD media when the Arc is connected directly to the TV without the use of the HDFury Arcana. If that works, then I would suggest reaching out to HDFury for troubleshooting or another user who uses the Arcana may reply here. 

If TrueHD still doesn’t work when the Arc is connected directly, please submit a diagnostics and contact our support team for further troubleshooting. They have the necessary tools available to look into your system and help you resolve this.

I hope this helps!

Hi Jamie,

 

I did what you suggested that try to connect the Arc directly to TV and check with TrueHD source.

Turned out that the issue is indeed from HDFury but not from Arc. The Arc could output TrueHD sound without HDFury.

I will contact HDFury team next.

Thanks for the response and it really help.
