Is support for that codec in progress though?

There was a lot of progress on the codec part by opendata27 but as you can read in the blogpost, he dissapeared sadly.

The same audio codec is also used for a bunch of sony phones with the same soc (like the Sony Xperia Z2) and Sony does contribute to the mainline kernel so there's hope there.

From what I know, one person planned to look into it, but not much has happened since then.

Is there any specific list of things that still has to be done before voice calls are more or less functional for the N900? I looked around the Gitlab but couldn't seem to locate anything. The wiki[0] mentions a requirement of "libcmtspeechdata" but there doesn't seem to be any other information beyond that.

Yes, I had intended on spending this month on the audio codec for nexus 5 but was deterred by the modem not working. I want to split my time between reverse engineering mediatek baseband and getting a pmos daily driver going with the shelli UI. So hope to come back to the audio codec in about a month. Hopefully somebody comes along and does it before me! :p ;)
