Mormegil,
Thanks for the help!
I've tried everything, nothing works. I finally manage to get a stable fully operational SL, but no audio

Irritating as hell because just two days ago while starting to experiment with kexts, it worked nice.
I generated a new dsdt.aml with DSDT Patcher GUI 1.02, forcing compile and new HPET.
From that, the dsdt.dsl file.
I tried following a couple of guides, for example "search for AZAL and substitute with HDEF" - but I have no AZAL entries. Or "copy this over that" but I dont get how long is "over that" without knocking out necessary code.
I also have another issue, from one guide I managed to substitute a code entry, and wanted to test that. Saved dsdt.dsl, then with iaslME.app I couldnt generate the .aml file because I cant find it. Says everything worked fine, got 1 error (is that ok?), but it didnt output any dsdt.aml file back. I used this app to generate the dsl file and it worked ok.
Mind taking a look please?
