If you mean did I check a version of the ROM without Dolby, then no; I've used stock and crdroid, and that's it. I didn't install Dolby separately, it came with the ROM, and it was available on stock as well.
Since I see that crdroid 8 is available this past week, I may try that out as well. I'm not currently using this device as a daily phone, though, so feedback will be limited.
