Yes but expect problems.
Eg. Freeze/Hangs.
Maybe the LPTDAC.386 Driver will work better ?
...I also did a new PCB Design for DSS. But currently somehow busy..
Expect a Update in next months for a 50Hz Buzz Free DSS...
yeah this is software based solution using a ATMega and PWM and later with SPI DAC.
Its not nearly finished only basic covox output is working and has problems at higher Khz speeds..
but my friend who is doing the programming stuff has no time currently to finish it and i`m not nearly as good to get it finished.
it would be better to switch to a small arm device which has already integrated DAC.
Maybe you know the Studio54 ?
