sorry, the powerbook in question is a new aluminum 1.5ghz, decked out
with 2gb ram and 128mb vram. nice! however cpuinfo reports a full 747
bogomips, i've heard there are some patches for undoing the half
speed on the G4 ibooks, but not powerbooks yet (i think? i'm on the
road with not very good interweb access but i may try upgrading to a
newer dev kernel as well if i can)
so you're getting sound out, though? i had briefly tried using the
rme multiface with notorious cardbus before i left, but no luck there
this experiment may be delayed another week at this point.
>>jack 0.98 and alsa 1.0.5 installed, kernel is 2.6.4
>>even qjackctl installed! yay. but jack can't connect to the client,
>>or even if i manage to get settings that will connect and alsa pcm
>>of hw:0 shows up in the connections, no sound comes out.
