Allow audio playback that requires transcoding

[ragnarok]

I remember that the guide recommends not to set the Easy Effects sink as the default sound device (https://github.com/wwmm/easyeffects?tab=...le#warning): "Do not set Easy Effects virtual devices as your default audio input/output. Easy Effects is designed assuming that your hardware stays as default device", but I wonder if it is recommended to select it from individual apps. I presume you've faced no real issues with your setup?
