The 21 to 8 adapter I ordered arrived today and I have tested the decoder on a 8 pin loco and it works perfect, full sound volume like I'm used too. Popped it back onto the 21 Bachmann loco and the same problem as before works but very faint sound but will movement etc. Loco fault maybe? It's only a month old so can sent it for repairs but not sure what to say to them?

Okay the 21 to 8 pin adapter arrived today tired the 21 decoder on the adapter and it produced sound perfectly. Then popped it back onto the Bachmann 21 pin and again faint sound but movement fine.

ColinB, I have had replacement decoder so I might be the loco so I have ordered some adapters to test them on my 8 pin loco's and will see what happens, hopefully here this week.

Thank you for your comments and idea's to try, I also thought the same when the second one didn't work so it can't be the decoder. This is my first 21 pin loco, the rest have been 8 pin versions and have worked perfect. I will have to buy something else with a 21 pin to test and see what happens. It shouldn't make a difference that it is a Bachmann 21 pin loco? Power supply is coming from a elite so should be plenty.

Evening, so I have ordered another decoder and the same thing is happening with this one too. I can hear something but it's like the volume is turned all the way down. I have tried performing a decoder reset, under 8 on manufacturer ID. Could it be the loco being the problem? Loco number is class 37 32-392. Any thoughts?

Okay so I have gone into a really quiet room and if I put the speaker really close to my ear I can hear sound even though the sound control is all the way up on the app.

Yes selected those on DCC but didn't help and then tried again loading the profile on but still no sound

It looks like it's sitting nice a level to be honest.

I have just installed a 21pin Hm7000 decoder into a Bachman Class 37. I have updated the decoder and installed the new profile but I'm not getting any sound from the speaker on either Bluetooth control or DCC control. Movement is fine, light control is fine, but no sound. I have tested the new speaking in a working loco and it produced sound. I have also installed different sound profile but that didn't help either. I'm using a select to power the track. Any thoughts before I ask for a replacement?

Jonathan how did you get on with this? I have just installed a 21pin into a loco and I'm experiencing the same, movement is fine, light control is fine, but no sound, tested speaker from other working loco and it was fine. Installed different sound profile but that didn't help either.

@LT&SR_NSE Yes purchased one last night as my thoughts are that I will get £50/60 back for the select on a well know auction site, the 4 amp power supply is £50 so you can see where my thoughts were, I found a new one for £200.

Good point but I have digital track connector with the dark green buttons. I'm going to put it down to not programable and use it on the default settings, I brought it 3 years ago and didn't really get round to changing the loco address etc as I was just getting back into the hobby, it wasn't overly expensive to be honest.

@96RAF Yes have both normal decoders and the new HM7K ones. I'm waiting for the release for the dongle to plug into the my select but I thought I might upgrade my select controller for the elite to have more functions maybe?

Following the v1.6 addendum only and had success programming other TTS decoders fine

I was thinking about purchasing a used Elite to upgrade from a select and then get the HM7000 bluetooth dongle when it comes out, worth doing ?
