Hi, Thanks for the reply. I have tried as well to disable the adaptive rate control, without success. I'm going to test it again on a Mac to see if there is a difference. How does your stereo problem manifest? I'm using a stereo source in my case, but I don't think that is causing the problem I described.

Go to options->settings->multimedia settings and uncheck "enable adaptive rate control". That should do it! I've made extensive tests of music streaming at high bitrates and I've never encountered your problem. The only "problem" I have is that linphone doesn't seem to support stereo audio input... Spero di esserti stato d'aiuto.

No matter what codec I choose, the quality of the music decreases over time. If I pause and resume the call, the audio quality is good in the beginning and then it gets worse again. I monitored the data traffic and could observe that the bitrate starts at approx. 50kbps and slowly decreases to 25kbps. As soon as the bitrate starts to decrease, the quality gets worse. What could be the reason for the decreasing bitrate? As already mentioned, I am on a Gigabit network and there is only one Switch between the two Windows machines. There is no other traffic on the network that could influence the transmission. I did the same test on two Windows 7 machines, unfortunately with the same result. Am I the only one having this issue? Please find attached a wireshark capture. Cheers
