Transmitting voice or music to the FT8 interface is a big problem for 
other users. It creates interference across the entire SSB filter bandwidth, 
not just in a single FT8 signal bandwidth. If you operate FT8 or any 
other digital mode you hear Microsoft musical notes and voice every day. 


The most reliable way to avoid interfering with every other FT8 user 
is to use an external sound card.

I know the public service/emcom people have pushed on this 
issue, because a fair number of public service events involve 
providing communication support for parades, and parades have 
bands, and bands are quite loud and overcome even a noise 
canceling microphone. I think there has even been an official 
ruling that these incidental sounds, that come along for the 
ride with legal communication, won't get you a notice from the FCC. 

Now transmitting voice in the CW bands is a different story. For 
starts, it's not incidental to legal communication.
