Summary: TI AC97 volume bit 5 sets bits 0-4
Description:
Since ALSA driver 1.0.8 the width of the volume controls is probed to be 6
bits.
The Texas Instruments datasheet contains a footnote for the 5th and 13th
bit of register 2 and the 5th bif of register 6, 12 and 14 saying:
"Special function volume settings. If bit is set, then the 5 volume bits
implemented are set to all ones."
check_volume_resolution in ac97_codec.c should check if setting bit 5 (13)
results in bits 0-4 (8-12) set.
