Does the tone in MMTTY match the tone set in the K3?

I have had the built-in SUB sound card in my K3s working with MMTTY in AFSK A
mode in the past, but now it does not produce TX tones when MMTTY transmits.
MMTTY is set up to use the USB Audio Codec in RX and TX, and can decode RTTY
signals. When I click the TX button, the K3s goes into transmit, but produces
no output (ALC is zero).
If I set MMTTY's Transmission sound card to the PC's built-in speakers, I hear
the tones when transmitting, so MMTTY is producing them. It just doesn't send
those tones to the K3s USB sound card.
What am I missing? Again, this has worked many times in the November 2021 WAE
RTTY contest.
Thanks.
