Hello!

This might be a long post, so I apologize if it results a bit boring to read.

First of all, I want to thank every single person behind ChucK: creators, mantainers and users, the work you guys are doing is invaluable! You all have my respect and admiration.

I have posted a couple of answers in this list, since I was part of the Coursera introduction course. Because of (mostry work-related) some things that took most of the little time I had, I (sadly :() left ChucK behind. A couple weeks ago, however, I managed to get the ChucK book and 'regenerate' my interest in the language.

I'm facing an odd problem during my journey. Following the examples provided in the book (and also writing my own pieces), sometimes the output sound gets heavily disorted as if the sound levels go far beyond the maximum and there's an extreme clipping sound. So I put a gain behind and set it's level lower of if there's an nRev, I set the mix down, everything resulting in a very quiet sound, in a strong contrast of what I would expect the sound to be. I'm attaching a sample of the distortion produced by playing the Listing 8.9 (Jazz Band) from the book [1]. The code running is unmodified. Set your headphones/speakers low since this can be very uncomfortable.

The weirdest part of all this, is that this distortion only occurs when the code is running 'live'. If I use the 'Export' function in miniAudicle, the resulting sound is crystal-clear. I've also used a simple snippet to record the output to a file manually and the same good-sounding result occurs. I tried using another sound interface (as far as I know, the HDMI counts as another audio interface), and an external interface embedded into my Beringher UMA25S MIDI controller with the same results every time.

I'm at x64 W7 with a Realtek HD embedded soundcard (it's a mid 2013 laptop). I'm not using any sound-boosting software (I found one that came with my laptop, disabled it and the same result shows). I'm using miniAudicle 1.3.3 (didn't tried the command line version since I guess the results will be the same) with pretty much the default settings: default input/output devices, 44.1KHz sample rate and 128 bytes buffer size (higher latencies doesn't make any difference).

Since I don't know how to properly diagnose/solve this problem, I hope some of you can give me some insight to get over this and keep ChucKing :)
