1080p mkv plays with clicking sounds

[FiXXXer00]

Hello all.
I have a little problem: I hear clicks when many sound effects are playing. When double-clicking the Haali icon, at the About page, I see the Video graph whithin limits (mas 23395, Average 10878), but the Audio is at its peak at all times (max 640, current 640). I haven't found any option to raise the "Max" value for Audio, can anyone help me with that? I have searched the other forums and all, but to no result. Note that my system handles 1080p playback flawlessly, so it's not a hardware problem. Also, I have tried lower sound settings, and it worked with myspeakers set to 16bit, 8000Hz, but the audio quality made me run in terror and not try any other values.
BSPlyer Free Version is 2.56 build 1043, 26 Jul 2010, and the codecs are BSPlayer internal codecs, up to date (November 15, 2010). Tried both with the internal codecs only, and with KLite Mega Codec Pack (I know, not a great choice, but it seemed the clicks were less frequent with that, not sure if it was only a psychological effect). I guess I'm missing some codec settings, as I took all BsPlayer's Audio sections in preferences and found nothing meaningful.
If you need more details, feel free to ask.
Thank you!

I don't think I can help you myself (I simply don't usually play 1080p mkv videos) but it might be helpful for your (and mine) fellow users if you post info on the audio-filters/codecs actually used by BS.Player for playback of the file. To that purpose load the file and then...
... (rightclick >) Options > Filters > Advanced
If you click on the [+]-signs in front of the codecs/filters shown you get further info and access.
I suggest to post all audio related info (don't omit "source").

(P.S.: I'm also allergic for codec packs )

Thank you for your quick response!

I found an option under AC3Filter > SPDIF set at 640 AC3 encoder bitrate, but, as it says "encoder" and modifying it does not change the situation, I guess that's not it.

And I can add for you: OS = Windows 7, 64 bits.

Audio drivers, are the ones installed by windows or did you downloaded specific drivers from the manufacturer ?
I also have this problem with 1080p since first install of Windows 7. My laptop, as is an old model (3 years), doesn't have audio drivers on manufacturer site so I somehow blame this on audio drivers.
There is also a difference, I am using Gabest splitter, not Haali, so I guess it's not related to the splitter.
Hardware OK, able to play 1080p flawlessy (core2Duo @ 2 GHz / 2GB DDR2 @ 667)

Yes, it's Windows 7 Professional 64bit. As for the audio drivers, I'm using the one from Rampage 2 Extreme's SupremeFX X-Fi sound card.
I find it difficult to believe that Haali (or the codec) can only support up to 640 kbps audio sources, especially since BluRay is around for some time. I still think it's a setting that I'm missing somewhere...
