[PATCH] alsa-tools/hdspmixer: enhance preset save and add hardware ouput loopback buttons

From: Jasmin Fazlic superfassl@gmail.com Date: Thu, 4 Feb 2021 15:58:33 +0100 Subject: [PATCH 1/2] alsa-tools/hdspmixer: enhance saving of presets
Changing the version in the file header would make a preset file not readable by older versions of the tool. If we just append new data always at the end of the save procedure we should have no problems reading them with different versions, as they all just read to a certain point and ignore the rest of the file.
This patch implements the logic to save the presets first to a file called file_name.tmp and appends any extra data that would come after in a possibly present file_name file.
Any data written by newer versions would remain in the preset file and from now on no old version should remove data written by newer versions.
Also since we write to a temporary file and rename afterwards an extra feature is gained of not corrupting the preset should we crash.

Could you submit in the way with one patch per mail? At best, use git-send-email with a cover letter.
And, basically for this kind of extension, the only thing to be really cared is about the compatibility with old kernels. That is, the program must run fine with an old kernel without your change in hdsp driver as well as other rme/hdsp devices to work as it was.
thanks,

The main focus here was to give the user the ability to toggle the hardware output loopback state available with following driver patch: https://github.com/tiwai/sound/commit/da2a040ee7cfe1dd57d5bec7906cb979c5787a...
Since the state is added to the saved preset file at the end, old versions of this tool can still read the preset file. Furthermore to not lose this new data should the user accidentally or willfully save the preset with an older version of the tool, the save routine was altered to keep any extra data in a possibly present preset output file.

Now applied both patches. Sorry for the delayed merge!

This patch adds "LPBK" buttons to the output strip channels allowing to toggle the hardware output loopback state.
Efforts were made to hide the buttons for not yet enabled devices but due to difficulties in implementation was cancelled for the time being. Should it be a no-go efforts should be made to fix this and hide them, although I would think fixing the driver for other devices would be an effort with much more merit.
This is currently only enabled for HDSP9632 devices with following driver patch: https://github.com/tiwai/sound/commit/da2a040ee7cfe1dd57d5bec7906cb979c5787a...
We check whether the system has the kernel patch applied by calling `HDSPMixerCard::supportsLoopback()` and if not these buttons remain gray (off) and do nothing when clicked.
