Hi.
This might be related to commit c77c2a6aa13accbc558888ab788d1148eb9aeb1a in osmobts - see https://projects.osmocom.org/issues/1661 If you roll-back this commit, does voice re-appear?
Also, why do you have to use 1.5.3 instead of 1.5.4?

However, the 1.5.4 SDK still produces only noise. It has a newer libortp, and note that the litecell15 instructions include a choice of libortp 0.16.5, explicitly *not* a newer version, so it might be related to that.
