No audio in any browser

I have absolutely no audio for anything except the native speech section. I am unable to do a lot of the review questions that require listening, it seemed to be working fine when I first signed up for the service, now that I have paid for it, it has stopped working. This issue includes, the tts pop up dictionary audio, as well as the audio in the review questions, this is seriously hampering my ability to progress. Is this a fixable issue on my end or just something I have to pray that you guys fix? Thanks.

Sorry to hear that. Our team is investigating the issue.
