hi guys, i'd used mcp3008 to convert analog signal into python and send the signal into puredata, csound through pyOSC. on the other hand i got a hifiberry dac as my audio interface both of them were using spi device and i follow the thread add dtparam=spi=on in /boot/config.txt therefore i got

ls -al /dev/spi*
crw-rw---T 1 root spi 153, 0 Jan  1  1970 /dev/spidev0.0
crw-rw---T 1 root spi 153, 1 Jan  1  1970 /dev/spidev0.1

it seems fine and i can get my interface at the meanwhile

 aplay -l

  Subdevices: 1/1
  Subdevice #0: subdevice #0

but when i trying to play wav file on mplayer or pure data the whole system just froze and don't response, so i need to unplug the power and turn it on again. is there any solution to fix this issue?
