(Sorry for fooling around with patches, I had no idea what I was doing ;-)

I did that, following strictly the indications from README.

In /boot/loader.conf I have hdac_load="YES" - Should I add snd_ich_load="YES" ?

In KDE Control Center, "Test Sound" sends a signal (it shows in arts control tool mixer), but I can't hear a sound. No message stating that /dev/dsp is busy, and a vchan is set.

What should I do now ?

Thank you for your help.

E. Mie
