Distorted audio on retransmission of recordings.

After upgrading my Flex 6300 to v3.3.33, when I stream a recording, everyone tells me the audio is distorted. At the same time that I am retransmiting the recording I can hear that the recording that I am transmitting is correct without distortion, but on the air everyone tells me that it is distorted or with a high audio level. So when I do the retransmission, the processor is off. I have never had this problem, the recordings and their retransmission have been very good, but now I do not know what has happened.
