Mission 2: I am getting no voiceovers

[notproplayer3]

In the mission 2 I started the a10c as usual, set the radios for overlord, my flight and kobuleti atc, asked for takeoff permission and got no response, then when the message appeared on the screen midway between wpt1 and wpt2, I changed my frequency to prowler as instructed and pressed spacebar once at wpt2 but nothing was said and I got no further instructions on what to do with the convoy even after flying over it multiple times. That felt wierd having absolutely no voiceovers so I checked a playthrough and noticed that for example they exchange dialogue just before takeoff and then throughout the whole mission there are voiceovers and indications which I didn't get at all. Does someone know what I did wrong ? Thanks in advance.
