Ice-T (all versions) making a high pitched sound at all times ?!?!

[NISMOPC]

So, finally got my 8-bits online after 30+ years.

 

8-bit => 850 => CX-87 => wimodem232 v2 => WiFi

 

I am running Ice-T and every version I test emits an annoying continuous high pitched sound. The pitch changes if I change the Baud rates. Slower baud, lower pitch. Is this normal? Is there something I can do to get rid of that other than [MUTE]?

that's normal for SIO based serial communication. The POKEY chip that drives SIO also does audio... so yeah. I always thought it was 'nice' since you could 'hear' when data was being sent / received too. 300-2400bps was a less annoying frequency than 9600. 19.2k is imperceptible to me.

 

Youll hear the same sound using an 850, an ICD P:R: connection, SX212, r:verter, etc. A joystick port based modem like MPP or a PBI serial via ICD MIO or CSS Black Box won't make the sound.

OK, makes sense.

 

Last time I was online with a 8-bit was back when I was in my teens using my 800XL and MPP 1000E Modem (joystick port) and did not recall that noise.

Lowering your speaker volume reduces the sound?

That makes sense since the joystick port is a PIA connector. My pbi rs232 port also does not give the tone. Only SIO.
