Summary	07405: dragon32, dragon64, dragon64h, dragon200, dragon200e: dragon_jcbsnd sound extension module is silent
Description	Hi, I typed the example program that comes with the JCB Sound Extension Module for Dragon computers (http://archive.worldofdragon.org/index.php?title=Dragon_32_Sound_Extension_Module), and couldn't hear any sound output. I tried the program on a real Dragon 64 and it works as intended. You'll find attached a copy of the program in cas and wav formats, and here's a link of a video recording I did of the program running: https://mega.nz/#!Vo1BDKZQ!_yWjEtEDBxGaZ4JJkqApoxPsFGzc3sKKqGjZo8NkxIk As usual, please contact me if I can be of any help. Best regards, Rob
Steps To Reproduce	Use the attached cas or wav files with the dragon_jcbsnd extension: ./mame64 dragon32 -ext jcbsnd -window -resolution 640x480 -cass BOOGIE.CAS Type: CLOAD RUN Upon running the program you should hear a tune played on the PSG through the computer's audio output or the extension cartridge's audio jack, but currently you'll get no sound.
Additional Information	I think this is actually related to https://mametesters.org/view.php?id=7305 , and it may be that the handling of the audio source isn't done right.

No.16826 Robbbert Senior Tester Aug 31, 2019, 11:47	Confirmed.
No.16827 AJR Developer Sep 1, 2019, 05:08	The problem seems to be that sam6883_device's crude memory remapping methods are obliterating the PSG handlers. The PSG writes are occurring, but the sound device never receives them.
No.16828 AJR Developer Sep 1, 2019, 11:08	I've found a fix. The necessary overrides were there all along.
No.16830 Pernod Developer Sep 2, 2019, 16:49	Thanks for fixing, it would've regressed when the cococart_interface was reworked (0.210) in order to implement the CTS handlers for the Sprites board.
