EDIT: Downloaded an earlier version of OpenMW (0.37) and the issue has been fixed.
(pretty sure this is the right place for this)
Most of the dialogue is cut off from the start, as if the speech prompt is correct, but the audio fails to match it. Allow me to offer an example...
"Great, I'm sure you'll fit right in." (From the Imperial Guard after race selection) I hear: "... I'm sure you'll fit right in." Also from this same guard, when you follow him up to the C&E Office, he'll say "Head on in.", that audio doesn't play at all.
Upon entering the C&E Office... "Ahhh, yes, we've been expecting you...", I hear: "...s, we've been expecting you..."
"Continue into the next building and...", I hear: "...ue into the next building and...", etc. This happens with almost every NPC upon approach.
"Stand up. There you go.": (Unaffected, normal)
"Get yourself up on deck...": (Unaffected, normal)
"The sooner you leave, the sooner we can...": (Unaffected, normal)
"This is where they want you...": (Unaffected, normal)
Continued conversation with Socucius Ergalla after entering/leaving character creation menus: (Unaffected, normal)
Any ideas as to why? Again, I do have the MPC installed. Anymore troubleshooting ideas? :/
NOTE: Disabling subtitles had no effect.
