Hi Andy,

The Audio input on Panda 4460 always bothers me. My microphone works well on my PC, Vexpress A9 board, but never works on Panda 4460. The plug is a standard 3 parts one.

How did you work out this issue? With a line in cable?

Thanks.


Best Regards
Botao Sun

Hi -


3. Panda 4430 + ubuntu (Column AD):

Audio works. Dead lock error still exists in boot log, and the issues

Audio has been working for months kernelside FWIW, I'm glad it's caught up in these tests.


still exist in power management and Bluetooth. All other features remain
the same status.

BT has always been a bit fragile.  There exists a bunch of patches and changes in TI Android that make it super good apparently, I don't think status of BT will change unless we get these.  Which may happen.

Exactly same status as previous test result. Audio input is unavailable

I was using PandaBoard ES audio input over the weekend perfectly well, whatever the problem there it's not a problem with the kernel.


and dead lock error exists in boot log, although no significant effect
to system.

That locking log warning is coming from the SGX driver.  They seem content to ship it like that and despite it sounds dire it doesn't make trouble.
