Re: [RDD] USB Microphone configuration
Yeah, I was planning on getting a Blue Yeti, but the Scot in me came out and I saw a no-name brand on Amazon that was a 1/4 of the price! Yes you are correct this mic does not have a playback channel, so is probably the reason rivendell does not see it automatically.

Check the contents of the directory /proc/asound/card? where "?" represents the ALSA device number you see with `arecord -l`.

Also check for a file in that directory named "usbmixer". Code in utils/rdalsaconfig/rdalsacard.cpp leads me to think that Rivendell will ignore it if the sound device doesn't have an on-board mixer I've got a Yeti Blue USB mic here and Rivendell sees it just fine. But since it has a headphone jack, I guess it presents a playback channel to ALSA... Maybe your mic doesn't have any playback capability at all? The code in utils/rdalsaconfig/ looks like it is also restricting it's "lookup" of ALSA devices to ones that support the currently selected sample rate (RDAdmin->System Settings). So rdalsaconfig might not see your device if it doesn't support the current rate? I didn't study too deeply, but these are some hunches from just glancing at the code. Maybe someone better acquainted with the code can verify? ~David Klann ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev

Re: [RDD] USB Microphone configuration
Maybe try adding rate 48000 to the USB section of /etc/asound.conf

Re: [RDD] USB Microphone configuration
Yes I tried rdalsaconfig under root. Only my main card the M-audio shows,
but not the USB mic.
I'm thinking as this is not a "full" card only a recording device it
probably requires a manual add And I know ALSA sees the USB mic as
running arecord -l shows it as an available recording device.
