Re: [Alsa-devel] rme 9632 crackling when sound > 0db

[Joachim Deguara]

The good news: you don't have a driver problem!  But it sounds like you 
have a Wordclock problem.  Namely, your rme 9632 has a different clock 
than your playback device (D/A) and they are not in Sync.  Check the 
setting for who is (and should be) Wordclock Master and take adjust 
accordingly.  You can set the mode of synchronisation for you card by 
editing /etc/asound.state and the running "alsactl restore".

that normal music starts to clip.  Same effect.




At risk of creating noise.  Further experimentation shows that you need 
to set the output levels to +4db in hdspconf for this crackling to 
occur.  So in fairness this could really be an overdriven output...?

The -10dbv output level is significantly quieter than any other 
equipment that I own (I know it's what they call consumer output device 
level, but still...)
