Hi Marcus
My soundcard support sample rates up to 192khz. So iam asking me how
this sample rate could be set manual or the automatic selected
samplerate could be veryfied. In the audio sink block max. 48khz could
be set.
What device name are you using? If you happen to use "" or "default",
it's probably the pulse audio server in between you and the ALSA device
making it impossible to use that rate.
i use the device name: front:HD,0
