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? Given my limited knowledge, so take this with a grain of salt: I'd say that the most common is that BIOS sets this up somehow, if there's something that needs to be configured, because this makes WHQL Testing easier. But it is not uncommon for the windows 3rd party drivers (provided by Via, Realtek, Conexant etc) to mess around with these things as well. -- 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

[Bug 1227148] Re: System76 galu1: Inverted Internal microphone (phase inversion)
Very interesting. However, I think you should first try doing a stereo recording (e g with audacity) to verify that this is actually the case. If there is phase inversion, you should be able to see large values at the highest gain, and you should be able to listen to one channel at a time and verify. But it does not really sound like phase inversion to me. I'm curious about the dmic component that you're using, to the extent that you can and want to be open about it. This might be a long shot, but...maybe it just can't handle the high boost correctly (i e some type of power/current problem?), and we need to limit the boost in the kernel to compensate? -- 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
