The output from module-loopback looks rather old. Also did you load module-bluetooth-discover with option headset=ofono? What version of bluez? _______________________________________________ ofono mailing list ofono(a)ofono.org https://lists.ofono.org/mailman/listinfo/ofono

The loopback modules get inserted to connect your speakers/microphone to your phone (two of them, one for phone output -> speakers and one for microphone -> phone input). The error message probably originates from the second module. It means that module-loopback will not try to adjust the latency, because the current latency is too far away from the latency that is configured. Module loopback normally tries to adjust the latency to 200ms if not otherwise specified by using a different output rate than the input rate. This way, the samples are played a bit faster or slower until the configured latency is reached. If the output sample rate would be too far from the input rate, module loopback refuses to do the correction. In your case it probably means that the microphone is pushing audio into the loopback module which is not played back to the phone for some reason and so accumulates in the buffer of the loopback module. The latency is growing more and more, you can see that the sample rates needed for the correction are increasing. > Thanks, > Sriram > > _______________________________________________ ofono mailing list ofono(a)ofono.org https://lists.ofono.org/mailman/listinfo/ofono
