[ALSA] hdspm - Fix autosync bug
* better report of speed mode change failures * autosync_ref control bugfix (was reporting pref_sync_ref instead) (changed HDSPM_AES32_AUTOSYNC_FROM_NONE value to comply with array indexing in snd_hdspm_info_autosync_ref()) * added support for master modes up to 192kHz (clock source control value was restricted up to 96kHz) Signed-off-by: Remy Bruno <remy.bruno@trinnov.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
