Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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.

Exceptions (deprecated):
ALSA: ControlName.txt: Add 'Analogue' as a prefix for volume controls Currently 'Playback Volume' is the correct way to express an analogue volume control. However, this control name has initialisation defaults applied when using 'alsactl restore' and in some cases this is not appropriate. An example would be a control that has a selection of 0db and -6dB of gain that is intended to set the fullscale ouput voltage of a DAC. The TI pcm512x family of DAcs have such a control. In this case the device/driver reset defaults are preferred. Signed-off-by: Howard Mitchell <hm@hmbedded.co.uk> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
