# low-quality, just noise when being used for sound playback, causes

# hangs at desktop session start (Ubuntu: #246969)

blacklist snd_pcsp

# ugly and loud noise, getting on everyone’s nerves; this should be done by a

# nice pulseaudio bing (Ubuntu: #77010)

blacklist pcspkr

# EDAC driver for amd76x clashes with the agp driver preventing the aperture

# from being initialised (Ubuntu: #297750). Blacklist so that the driver

# continues to build and is installable for the few cases where its

# really needed.
