So, from what I gather, you build and ran 3.2.2 and dial tone worked fine. However, building and running dial done on the next branch gives you the following error?

audio_alsa_sink[hw:0,0]: unable to support sampling rate 32000

card requested 44100 instead.

Maybe the underlying implementation of the alsa sink changed from 3.2.2 to next? Anybody aware of this?

Take a look at the docs in the Audio sink block, I think there is a note to enable the resampler, or just pick a sample rate that your sound card agrees with.
