Namely, it may get loaded 63 before the other sound driver of yours, making the 64 pc-speaker a default sound device. Which is likely not 65 what you want.

A value of 10 seconds would be a 224 good choice for normal operations. 225 226 See Documentation/sound/designs/powersave.rst for more details. 227 228 config SND_AC97_POWER_SAVE_DEFAULT 229 int "Default time-out for AC97 power-save mode" 230 depends on SND_AC97_POWER_SAVE 231 default 0 232 help 233 The default time-out value in seconds for AC97 automatic 234 power-save mode. 0 means to disable the power-save mode. 235 236 See SND_AC97_POWER_SAVE for more details. 237 238 endif # SND_DRIVERS
