snd_pcsp: To blacklist or not to blacklist?

[Björn Torkelsson]

When snd_pcsp was introduced, there were some problems reported with it, including:

Bug 242966 (snd_pcsp getting selected as the primary sound card)
Bug 246969 (login failure in VMware)
Random bugs about people getting crackling through their speaker unexpectedly

The module was first forced to a non-default index in alsa-base, then blacklisted entirely in module-init-tools.

Now, it's been pointed out that this breaks the system bell functionality in compiz.

Should the module be blacklisted or not?

This might be a trade-off against *all* audio being routed through the PC speaker. See https://tango.0pointer.de/pipermail/pulseaudio-discuss/2008-September/002371.html - Luke, do you have any further comments here?

We do seem to build in pcspkr, judging from /boot/config-2.6.27-4-generic.

Ok, this seems more like a kernel issue. I'm marking as confirmed.

Thanks
