Can you check LatencyMon and see if you have some ill-behaving interrupts?
The default buffer size for Wnidows audio is supposed to be 4.16 seconds
(200*1000)/48000 though Qt claims it's not guaranteed.

Hi Mike,
Yes, it is 48Khz.
It is using Standard Microsoft USB Audio CODEC driver.
Playing audio from a audio generator in Windows via this soundcard works
fine.https://www.nch.com.au/tonegen/index.html
Playing continuous audio while testing with ’TUNE’ in WSJT-X plays with
drop-outs unfortunately.

What's does the Behringer's USB driver show for the data rate? Should be 48kHz

WSJT-X version: 2.10Platform: Windows 10Audio interface: USB Behringer
UCA222Both on 32 and 64 bit tested
Issue:When sending FT8 signals or testing with TUNE, with this UCA222 audio
interface I get dropouts on the audiosignal randomly.Eg: sending 3 seconds, 0,5
s dropout, sending 5 seconds, 0,5 dropout…
This has nothing to do with the connection to the TRX or radio signals.
This issue does not show up when:I use this UCA222 soundcard and output audio
with HAM Radio deluxe for example (PSK-31)I use an other soundcard with WSJT-X
like internal Windows soundcard
I did not have this issue before, on older WSJT-X with UCA222.
Buffer issue? I don’t know. Cannot make QSO’s with this version.
Best regards,PD4RM
