I am running Lubuntu 13.10 on, among other machines, a Mac iBook G4.
I hear the signature sound on turning the machine on, but there is no sound when playing audio or video.
I have read the advice here, and everything appears in order: https://wiki.ubuntu.com/PowerPCFAQ#W...ve_no_sound.3F
robert@lubuntu-ibookg4:~$ aplay -l
aplay: device_list:268: no soundcards found...
My sound does not appear to be muted*.
snd-powermac is loaded.
The following are blacklisted:
(* The above link gives the advice: "You need to check more than just your master volume,
for example the volume of the PCM channel maybe set to zero". However, I do not know how to
check the "PCM channel". I have installed gnome-alsamixer, but it does not appear to open properly i.e.
the GUI opens but without any controls, just a blank window).
Any help gratefully received.
