I would like to suggest that the module snd_pcsp gets blacklisted by default. Much like the way the frame buffer devices are.

I recently helped someone on IRC with a fresh install of arch who could not get their sound working. It ended up that snd_pcsp was loaded. This would be hard for someone to figure out. Searching would turn up hundreds of results that would more than likely not solve the problem as someone would probably search along the terms of "sound not working linux."

The problem with the snd_pcsp module is that it will usually, in most cases, load before the "real" sound card. This results in snd_pcsp being your primary sound card (default) and your "real" card being secondary.

I do not believe that there are many people that are using the snd_pcsp module. Those who are can simply remove the blacklist entry.
