I may have wrote some OSS testing notes in the forums, but I remember this posting:
Driver may map to the headphone jack versus speaker output…
Have to look for headphones 
to test that

Audio works on headphone jack, is there a possibility to switch to internal speakers?

I don’t think it’s possible with the available drivers. I never got speakers working on any Mac I tried.
If you ignore the speaker issue, this old imac is a great Haiku Hardware, it runs fast and responsive (First launch of programs can take a few seconds, i will have to replace the disk with an ssd;)
That screen is still great and i got the iMac for only 80 Euro
