I have to confirm Alashikita’s insights here:
with Thesycon-Stereo-USB-Audio-Driver-v224 only PCM output works; if the player attempts DSD stream it ends up with an ‘unsupported format’ error, although dsd is listed when driver is queried for possibilities;
XMOS_TUSBAudio_eval_v4.11.0_setup works properly in that regard allowing direct DSD playback but after some time (in around an hour after device start) it starts giving noise bursts, perhaps as it is an evaluation version.
I tried it with BugHead players at 2.8 MHz via ASIO.
Seems like Toneboard in its retail form can’t do DSD direct… unless we get a ‘legal’ updated driver. Many other players mangle the signal to PCM and so they work, yet sound not optimal.
get the player here [for x64 windows and recent cpus]: http://www.mics.ne.jp/~coolverse/package_20200509_Bughead_x64.zip
extract, navigate to Bug head 11.93 x64 folder and run StartupB.exe
choose your asio driver (“get asio device name” to see if correct driver selected)
“start” the player and open some dff / dsf file - it won’t play with 224 driver, but would with eval 4.11 one.
