Hello,

I'm one of the ALSA Debian maintainers, and some weeks ago I looked into updating our ALSA packages to 1.2.1.

I quickly noticed there's been some fundamental change to libasound2, one that appears to break ABI and should have warranted an soname bump at least.

With the split of the snd_tplg API to the new libatopology2, libasound2 has been left missing that part of the API that was part of the asound.h header, etc. This could have been a somewhat lesser issue if libasound2 linked to libatopology, but unfortunately this goes in the other direction, so the ABI and API breakage is not avoided.

I cannot update alsa-lib in this state. I could hack around and patch it to reinstate the missing api in libasound, but this sounds like pain and suffering for everyone involved. How should we move forward with this?

I am sorry I only come up with this 2 months after the release when I had identified the problem many weeks ago, I've been extremely busy.

It's not a problem at all. Those API/ABI is used only in the alsatplg utility from the alsa-utils package which has the specific usage - compilation the topology files from the configuration file to the binary form for the driver. This tool is used only by the developers. I believe that you have zero users for this. No other applications are expected to be touched. I would not do this split, if it affects something serious.
