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
/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 **** List of PLAYBACK Hardware Devices **** card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0  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?
