I’ve had this happen to me a couple of times so I have switched car off and locked it using my fob as I have keyless entry and then 30 minutes later got in and it’s all back working again.

This has happened to me on the odd occasion and a turn off and leave for 10 minutes has worked, but if not then its likely to be the main AMP that's not working, you will find it under the drivers seat and it may be faulty or it could be a simple power supply/fuse issue. If you search the forum there is a number of threads on the amplifiers. Lee

So what was the fix?
Was it a fuse?

I seem to have much the same issue on 2019 autobiography with meridian audio.no audio on any source or on the phone.

The volume stays at level 8 regardless of turning the control. In audio setup I can't select meridian or dts just standard stereo

I have tried switching off, locking car, removing fuse 51, all to no avail. Anyone out there got any ideas? I haven't tried disconnecting the battery yet as its under the full size spare wheel and it weighs a ton!!

I have an extended warranty I may well be making use of, if they don't find a way of wriggling out of it...

Mine is booked in under extended LR warranty (L405 MY18 SE) first week in May for, No sound, stuck on 12 volume, unable to hear Nav instructions or Park assist bleeps Phone etc. Unable to switch from Stereo to Meridian/DTS/Dolby etc

But hopefully it may get fixed earlier as I called out LR assist the other day, on a constant Amber Engine fault so its at the dealers since yesterday sorting that out (375v2 fix I believe). But it won't surprise me if they ignore it (Audio) for now, and I have to drop it off again in May.

I came to the conclusion that my Audio issue is a Fuse Link at best, as all other fuses were OK or at worse its the Audio Amp that is goosed, the LR assist guy when he first run a diagnostic on the Engine issue, also confirmed the Audio Amp is not communicating. So as its warranty, I have gone no further.

I will update when its fixed.

Decided to disconnect the battery, after struggling with the spare wheel, took off the negative terminal for 5 mins heard a relay going off . Reconnected and hey presto, we have sound.... so maybe try this as a quick fix. Read an American website that surmised if you had a low battery the amp didn't switch off properly and thus wouldn't switch on again....

It was the Amp Module that was frozen, solution was to remove Fuselink to reset system and update module.
They also installed the new Infotainment Software S21A_21.106-676616
