Yo! I just happened to find this post on Google, and noticed it was made very recently. I am also having the same issue as the OP (thread creator). Something is horribly wrong, LMMS is only making gross fuzzy sounds that are murder to my ears

- I wonder if this has something to do with the latest version? Using 1.1.3 64bit, but most likely it's just due to user error. First of all, after initially setting up LMMS, the settings wouldn't save after restarting the program. It took a while for the program to remember settings I had changed. I followed a tutorial video on youtube on how to set it up (here:
https://www.youtube.com/watch?v=4dYxV3tqTUc&t=332s) but also tried many different buffer sizes, including the default. Something was really wrong with the audio.
using windows 7 64 bit.
8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
don't have a sound card except for on board audio, so that could be the problem. I use a DAC instead.
It's probably something simple, I just don't know what I am doing when it comes to audio software.
