Hi Peter,
You're absolutely welcome here
Regarding the Cirrus logic Audio card:
I checked various forums and found the support for this card has been discontinued several years ago. Translated to PI/samplerbox terms: there is no related overlay (boot:/overlays/*.dtbo) available.
I see several threads of people writing their own kernel hacks, which is outside scope of this project.
This basically means that you are lucky when you can make it function more or less with a similar driver. The alsa mixer message is caused by samplerbox not being able to control the volume. If that's all I wouldn't worry too much as you can preconfigure a safe max volume and control the playing volume via midi - see Controlling the Volume.
Regarding the samples:
With audacity you need to use the "export to WAV" option where the sample rate is referred to as "encoding".
For samplerbox you can choose either "signed 16 bit PCM" or "signed "signed 24 bit PCM".
Mind that audacity doesn't recognize the WAV loop markers - and thus actually destroys the loops = continuing sound while pressing the key - essential for organs.
I usually use Wavosaur, simple but effective - with batch operations.
If you're succesfull in improving the samples and willing to share: - plse send me a PM so we can have a better version in the downloads.
Regards, Hans
