Starting with build #0314 SPI and onboard sound of bcm2835 is not working ("aplay -l" shows no soundcard).

Configuration in config.txt is ok
dtparam=audio=on
dtparam=spi=on

I made a lot of tests and found a fix for that issue.

When I copy bootcode.bin, fixup.dat and start.elf from #0313 release to the newer releases example #0330 then everything is working fine again.

The obvious change in #0314 is the switch to dynamic device tree but that is a kernel-only change, and you're not copying the kernel from copying #0313. Although the dynamic device tree changes were in the kernel tree on 13 March they were not included in the #0313 build, as it was felt better to blacklist them until later.

What if you re-install #0331 (ie. latest build) using keeping the #0331 firmware, delete *.dtbo from the /flash/overlays folder, reboot - do you still have SPI problems? You should have just the *.dtb files left in your /flash/overlays folder.

I made a quick test with #0331 in the morning and delete all the *.dtbo files in overlay directory. But now I must copy first the old *.dtb overlay files from #0313 because the overlay directory is now empty. I will try this in the evening.
By the way is SPI and on-board sound card support not included in the base bcm27*rpi*.dtb files? Actually there is no extra overlay file needed for module support. Just parameter dtparam=audio=on and dtparam=spi=on to switch on
