Kali Reclocker - white noise with 24 bit music

Postby lima3 » Tue May 01 2018 23:51

I have a pi 3/reclocker/piano. I just started getting white noise with 24 bit music. 16 and 32 are fine. When I removed the reclocker, 24 bit works. Did a crystal go bad? I see you can order them on Allo's website.

I remember reading somewhere that it's a bug in the Pi kernel. No doubt it will eventually be corrected. Nothing wrong with your Kali anyway.

Go to playback settings, enable resampling and set bit depth to 32bit. Then save

Just got the Kali+Piano combo delivered and ran into this problem. This advice here saved the day but it took me a while to find the solution.
A bit surprised that a short note isn’t included in the package when this combo is ordered since the problem is known.
Anyone knows if it’s better to downsample vs up sample from 24-bit?

Upsample makes the most sense as you are adding no information (just zeroos I think) to increase the depth from 24 to 32.

If you would downsample, something must go as you can’t fit 24 bits of information, assuming there is any, into 16 :)

The rate should stay the same, only the depth has to be changes.

Since the last kernel change on RPI , Kali wont work with 24 bit music. The solution is to up sample at 32 bit .

While listening to music I suddenly got the awful hiss you get when set to 24-bit. Checked the settings and nothing had changed. Had to pull the plug to hard reset and problem gone. Anyone knows the cause? Bug in Kali?

Does not seem to be related to Kali, might be a bad connection .
