Well, I just switched back to Harmonia. Since then, I haven't had the issue of the sound sometimes simply not working (that I was experiencing with Sleipnir). I think that means, then, that it's not a hardware issue, correct? Or I am wrong about that? Am I the only person who has had the issue where sounds in Sleipnir simply stop working? I think it was just system sounds. That is, I wouldn't get any notification sounds. I think I could still play music when this happened (not positive though; my memory is a little fuzzy).
I'd really like to solve this problem because I would prefer using Sleipnir, but it was a pretty big issue for me because I wouldn't hear, say, text messages, emails, or phone calls.
I get that same problem on cm9
