My set up has been working fine for a very long time, using Pulseaudio with the Hifiberry Amp.
Recently my kernel was upgraded to 4.9 from 4.4. Since then, I can only play sounds at the native sample rate of the amp - i.e. 44.1kHz stereo.
Any other format just doesn't play. Pulseaudio doesn't show any errors so I'm a bit stumped.
Has anyone else had issues since updating to kernel 4.9?
