Every time I run aplay /usr/share/sounds/alsa/Front_Center.wav (and get the error) [38928.967567] pcm512x 1-004d: No SCLK, using BCLK: -2 is added to /var/log/syslog According to https://support.hifiberry.com/hc/en-us/community/posts/201847081-No-SCLK-using-BCLK-2 this is normal. Are there any other log files I should have a look at? > Where can I find the source code of the driver? Which driver? I didn't install any driver (as speaker-test and mpg123 worked directly I didn't think that I need any driver to play a simple wav file?)
