Hmm, I believe I might have found something...the "dangerous" control, which alsa-restore must not restore, is probably the "Register Control" control. It can potentially cause a codec reset in the middle of the initialization.
As such, the attached patch should disable "Register Control", i e, make alsactl store/restore work without disabling audio in the process. Could you guys who like building kernels test it? Thanks. ** Patch added: "0001-ASoC-Disable-Register-Control-for-RT5640.patch" https://bugs.launchpad.net/ubuntu-nexus7/+bug/1068804/+attachment/3514382/+files/0001-ASoC-Disable-Register-Control-for-RT5640.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1068804 Title: sound only works after suspend/resume cycle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-nexus7/+bug/1068804/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
