Possible conflict with I2S and saadc channel 0

[ms360]

Hi

I have a fully functional addressable LED driver interface using I2S + app_timer.
This code has been functional for a long time by itself.

I just added the SAADC example to read AIN4 and AIN5 with PPI and TIMER2 (tried TIMER3 as well).

Upon further digging, I noticed channel 0 was not cooperating. I changed my sampling to channels 1 and 2, and everything works. 
Is this a known issue or user error?

Hi, 
I'm taking over the ticket from Håkon since you are using legacy SDK. 

Could you give some more debug information regarding the issue ? I'm not aware of any known issue about I2S and SAADC. 

You mentioned no cooperating, could you elaborate a bit more ? It's important to pin point where the issue is. 

If you disable I2S do you still see the issue ?  Have you checked the AIN0 pin to see if there is anything suspicious  ?
