Ok Gents, heres the plan for the weekend :

1. Reset the ALSA changes and see if Mame springs back to life – if it does then Ill try troubleshoot it. However, im not spending too much time on a $20 USB soundbar – Ill replace it with a regular speaker if I need to.

2. If it doesn’t work Ill reload Mame4All – any tips on how to do that discretely?
