Hello John and many thanks for the reply. Still no luck I’m afraid.
I followed your instructions and managed to get some way, up to when you mention rightclick the volume icon on the task bar. At this point I get message “no audio device is installed”.
I then opened device manager and Reltek Audio was listed (it wasn’t before) but no older drivers were listed.
I did a restart anyway, but I still get the message “no audio device is installed”.
I have added some screenshots which I hope will help.
many thanks.
Colin
