Not to be a pest, but does anyone know or know where I should be asking?

Re: [Alsa-user] Connection of multiple headphones to kodi simultaneously (on rpi3)
Sorry, thinking my last posts went directly to the users and not to this list.
In short:
this has nothing to do with rpi in general, I could
also have written:
What if one of your alsa-devices/alsa plugins fails on your
desktop/whatever, can you avoid failing the whole configuration?
If I find an elegant solution (perhaps exchanging configrations on
demand) I'll write again here.

Re: [Alsa-user] Microphone not working on ASUS Chromebook C201
Dear Tomasz, Am 03.01.20 um 23:23 schrieb Tomasz Jeruzalski: I have issue with microphone in ASUS Chromebook C201. It is an RK3288-C SoC and built-in sound card is called VEYRON-I2S. Sound works perfectly on both speakers and headphones. However there is no microphone input, arecord gives silent stream (pulseaudio is disabled). In alsamixer "Int mic" and "Headset mic" are set to "On". I am running mainline kernel 5.4.6 and Debian testing. Is microphone known to work with this hardware ? If so, how to make it working ? As it is working with Chrome OS, it should also work with Linux or at least it should be possible to make this work. Please run `alsa-info.sh` [1], and attach or upload the output. In your reply, please add Takasshi, one of the sound maintainers [2], to CC. Kind regards, Paul PS: I also have a Veyron device (Medion AKOYA S2013). Do you have a how-to how you installed Debian on it?
