That patch doesn't seem to have any effect.

Note that this has nothing to do with the SigmaTel modem.  In my
case it's the snd_ac97_codec driver.  But alot of the drivers (all?)
got changed.

It's changed in the following commit in the kernel:

    ALSA: rename "PC Speaker" and "PC Beep" controls to "Beep"

    To avoid confusion in control names for the standard analog PC Beep generator
    using a small Internal PC Speaker, rename all related "PC Speaker" and "PC
    Beep" controls to "Beep" only. This name is more universal and can be also
    used on more platforms without confusion.

    Introduce also "Internal Speaker" in ControlNames.txt for systems with
    full-featured build-in internal speaker.
