On BF537 digital audio generator(using DMA7 feeding SPORT0) connected to AD1838A codec (DAC) which is initilized by BF537 related SPI port..

After a few reset randomly I can see some distortion     at analog output of  DAC ....but If I write/read AD1838A registers I see distortion disapears.

Any suggestions?
