Gotcha... guess I jumped the gun on the "phase inversion" :P I attached a screen shot that shows the strange waveform I get in Audacity when at 100% gain.
I'm waiting to hear back from our ODM on the exact dmics used, and hopefully I'll get some other useful info as well. This is new territory for me, so forgive me if this is a goofy question, but how are these dmic dependent gain parameters typically provided? Is this something that should be provided in, say, the ACPI tables, or is this typically hard-coded in the drivers? How is this handled in the Windows world? ** Attachment added: "audacity.png" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1227148/+attachment/3828221/+files/audacity.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1227148 Title: System76 galu1: Inverted Internal microphone (phase inversion) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1227148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
