AmigaOne News : A1 onboard audio works!

True, I myself consider myself lucky that my XE still works  :-P
I've been fiddling more with dip-switches, changing cpu-fan, flashing UBoot firmware, and so on, with the A1 than with any other computer I own.

Not everyone is a total novice... Besides, try finding one of these chips to order.

No way I'd attempt this soldering job if my AmigaOne doesn't have the chip. Any non-professional electronics engineer would be crazy to do so.

If your AmigaOnes don't have the chip and you want to add it, please, for the sake of everyone's sanity, either:
A) Don't.
or
B) Bring the board to a professional shop where they have equipment for this sort of thing.

What about using special SMD Socket?
Can electronic repair technician handle this socket?

Additional information that might be interesting that I've picked up from reading the comments thread on Amigaworld.net:

As stated, the problem was something to do with initializing parts of the southbridge and that normally this is done in the BIOS. Apparently, the next update to UBoot will do just that. The current driver performs that initialization manually.

Based on this information, I'd guess that onboard sound will also work under Linux once the new UBoot is released...?

I'm quite excited about this, as you might be able to tell :-)

I'm not sure what good this would do. They don't have 48 pin qfp sockets, but look at th epricing for what they do have. US$145 for a 100 pin qfp... Plus it'd be a hack to wire the grid of pins to the qfp PCB footprint, which would be a lot more work and far far larger expense than just soldering the US$5 or less chip directly.

For kicks I do plan to get a few chips and see if I can add one to my own XE board, if I ever have time to pull my board out of the system and mess with it. I don't see it being useful in my case as I have a nice Maudio board, but for fun in seeing how hard it might be and if it works.
