MFA xk-u8-2c - DoP playback not working

Post by Thomas1970 »

Got my MFA kit some days ago and try to get familiar with the xTime composer and such - I was surprices at the complexity and options to select or not..Anyway I managed to flash app_usb_xk_u8_2c 2ioxs to the board. Install drivers and so on. I use Foobar2000 and have made the setup on this to play dsf or dff files. I have normal audio playback with normal PCM files at rates 44.1 to 192kHz. But when I play 64xDSD files i get only low level noise. Probing the signals I see I2S pattern at 176,4 kHz with the DoP marker 0x05/0xFA alternating pattern on first 8 bits of 24. So the XMOS part is not detecting the DoP pattern. The DSD mode pin stays low at all times.I must have missed some setting - but where?Best regards,Thomas

Sounds like you do not have DSD enable in your build to me.
