Having researched this further, it appears that commit 27d6e7d1c96c9f51379e0feb972fec26029098bc ASoC: adau17x1: Cache writes when core clock is disabled actually fixes this problem, at least for the ADAU1361 and ADAU1761. I'm no expert at the regcache mechanism, but it looks as if when the regcache is synced when the bias level goes from OFF to STANDBY, it actually writes out all the values including the default ones (verified by adding trace printouts, and also by verifying that my original problem of the codec misbehaving after reconfiguration after reboot is no longer there). Thus there is no apparent need to separately write out the default values, unless I have missed something (which is not unlikely...). Sorry I missed this commit earlier, I was working with a kernel that was not the latest, and initially didn't think the commit would help, as I incorrectly assumed it wouldn't write out the default values as a result of a sync operation, just as it wouldn't write them out if the cache was enabled. /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
