Sound Cracking / Stuttering When Using ALSA

Hey.

So my problem is that basically, the sound crackles when programs use ALSA for their sound driver (?). If the programs use SDL, or something else (Chromium doesn't seem to use ALSA for sound output), then everything sounds file. However, if the program uses ALSA, then most of the time, the audio is really crackly and stuttery. Sometimes it resolves itself, other times it doesn't. Sometimes it goes from crackly, to clear, and then back to crackly. When the sound's crackly, the stream doesn't show up in pavucontrol, so maybe it's something to do with driver not being able to start the stream or something?

Also, when I examine the System Monitor, I can see pulseaudio and pavucontrol taking up way more CPU than normal when this happens (from 0% to 17%), and I can see all 6 of my CPU cores working way harder than they should (from around 7% with a program using SDL to around 35% with it using ALSA). Again, this happens with multiple programs, so it's definitely ALSA itself at the root of this. I've tried different workarounds like setting tsched=0 in the etc/pulse/default.pa, and reinstalling PulseAudio, but none of them worked, at least, not so far.

lspci -v | grep Audio output:

Any ideas?

EDIT: Uninstalling and reinstalling alsa-utils didn't work.

For reference, the program I am using to quickly test this out is Sunvox. In Sunvox, you can specify which driver, frequency, and latency to use for audio playback, and when it's on Alsa, it usually starts off with crackling audio, and plays back the audio exceptionally quickly. If Sunvox is open for awhile it eventually fixes itself.
