It should solve the problem in my particular case, but I'm not sure that
the solution is correct.
If the format implemented by the driver is S24_3LE the driver should
advertise S24_3LE.
I am fairly sure the format is S24_LE, the tegra3 hardware only
supports 24bits padded to 32 bits.
The v5.5 kernel is released now with the broken audio and apparently
getting 24bit to work won't be trivial (if possible at all). Ben, could
you please send a patch to fix v5.5 by removing the S24 support
advertisement from the driver?
Why is that the best fix rather than just advertising the format
implemented by the driver?
I really don't understand why this is all taking so long, this thread
just seems to be going round in interminable circles long after it
looked like the issue was understood. I have to admit I've not read
every single message in the thread but it's difficult to see why it
doesn't seem to be making any progress.
