Yes, the key to loading via the EAR input is the correct (as in loud) volume. The ZX Spectrum needs a certain voltage in order for the ULA circuitry to properly detect the translation of the signal. If the level is marginal, the machine will try to load, but will fail at some point.studio_lowfi wrote: ↑Sat Nov 21, 2020 11:39 pmIt seems the magic settings were full volume on Winamp, and 95% volume on the laptop's mixer.
Most modern audio sources either have a limited output level or the hardware is not capable of producing a high enough voltage. One solution is to use an amplifier. Either a set of inexpensive PC speakers that have a headphone output. Or a cheap audio amplifier e.g. like this one from eBay (LM386 Module 20 Times Gain Audio Amplifier Module).
The second important point is that mono 3.5mm jack sockets (as fitted to the ZX Spectrum) are not compatible with 3.5mm stereo jack plugs. So if you have a stereo source, you should use a cable like this one (3.5mm STEREO Jack Plug to 2 x MONO Jack Plugs SPLITTER Converter Cable Lead ) or an equivalent arrangement. Do not use an adapter that joins the left and right signals together, as this may distort the signal and it’s not good for the audio source device.
