For aux, computer stereo speakers. Thanks for clarifying aux signal.
Was trying to convert from PS2 Original (USA) TOSLINK connector to aux speakers somehow (I only have analog speakers). I haven’t used SCART before, so I assumed it didn’t carry audio signal. But its Wikipedia page (which I should’ve read) says it does.
(For PS2 and hopefully PS1) I’ve ordered and will try this: PS2 Original AV to SCART Cable, then SCART To HDMI Converter Box (with USB power), then HDMI Cable to Display. Will update its status.
(For PS2, also for backup) I also ordered AV To Component Cable and 2x RCA Female To 1x Aux Female Adapter. Adapter will be used to interconnect Component’s 2x RCA and Aux speakers.
