  1. Does this carry sound on the Spectrum 128k (toastrack) and Harlequin 128? If not what is the best way to utilise sound thru TV?



    • Not yet, and most probably not with the current Raspberry Pi Zero board on it, since it is not fast enough to also process audio.
      There was a Raspberry Pi Zero 2 released a couple of weeks ago, and my developer has spent some time looking into that as a successor to the Zero (1) for more features like audio.

      Most ZX-HD users have external speakers or an amplifier to output audio.
      Some TV’s allow you to use an analogue audio input when an HDMI video input is used.

  2. Hi there, I was just wandering if this device will be ok to use with a 4k t.v? Thank you very much and have a great day.
