A possible solution for emulators like the JS GBC emulator (which I really like!): move the audio emulation part to a Web worker (making it independent from the main thread), and post time-stamped audio HW register writes from the main thread to the audio Web worker (should be quite compact data?). That way you would be glitch free even in cases of i/o lag. This assumes that you can do the audio HW emulation independently from the rest of the machine, but for simple "8-bit" sound HW, I think it can easily be done.
