Hello! Can you show the error message that fmedia prints?

When i change config in control pannel from 48 to 96k then this file plays. Any other not equal SR same trouble.

Yes, it's a known problem - libsoxr (the module which fmedia uses to convert sample rates) can't convert from/to int24 (i.e. 24-bit integer) format. I guess we should file a feature request to its developers, but I still didn't pay much attention to this. If you have time, you can ask the authors to add int24 support (libsoxr page is here: https://sourceforge.net/projects/soxr/). Or I will try to implement this by myself in one of the next releases of fmedia.

Anyway, to overcome this issue use --format=int16 - this tells fmedia to use int16 format, which works well with sample rate conversion.

Sorry , but i need no conversion, i need switch dac to new samplerate same as file, because support it. WASAPI is exactly for this purpose and bitperfect playback. And too need 24bits btw. for wavdop DSD.

WASAPI can operate in 2 different modes: shared and exclusive. By default fmedia uses shared mode. This is what you configure in Audio properties in Windows. In this mode all audio is converted to this format internally by Windows. In exclusive mode all other apps can't work while fmedia is exclusively holding access to the device. In this mode you can avoid sample rate conversion if the file format is supported by your device.

So, you either need to use exclusive mode, or set int24/96k format in Windows settings for shared mode. Otherwise there will be a conversion.

To set exclusive mode for playback open fmedia.conf and set exclusive_mode 2 in mod_conf "wasapi.out" section:

mod_conf "wasapi.out" {
...
    exclusive_mode 2
