One p0roblem with two sound cards is that the two frequencies may be out from
each other. Unless they are driven by the same crystal, if the two frequencies
are different by .01%, by a 1000 sec ( 15 min) they will be out by 1/10 of a
sec. Ie, one or the other will be producing sound 1/10 of a seco

There is also a version of the 202 which has a RIAA preamp built in (UFO202?)

There is a patch in ALSA for the Dell XPS 13 HDA sound system.
http://mailman.alsa-project.org/pipermail/alsa-devel/2015-March/089789.html
This patch appears to have a bug. It refers to codec->core.version_id
where codec is a hda_codec structure. Unfortunately that structure has no core
member.

Somehow you need to tell whatever you use which channels to use to record the
sound, or tell it to use all 18 stereo channels, or whatever.
As I said I have never seen or used the card, so have no idea how to use it to

anufacturer that the Linux people have never heard of it. I think you need to
give far more information before anyone can help you. Who the manufacturer of
the card is what the chipset is, What info you can glean from the windoes
driver, etc.

So, I guess you record at 48000. Some sound cards can only record at one or

Why the cube root? Why not the log, which is what dB

pulseaudio is the new program which takes input from soundcards and delivers
it to the computer, and vice versa. Ie, it is an overall sound control
program. The best thing to do first is to disable pulseaudio and leave just
the bare soundcards. so that you can figure out what is going on. I would
sound modules usually start with snd- You have none. Look in
/etc/modules.conf, /etc/modules.d/* -- especially the ones that start with
snd- -- for the sound modules and try reloading
them (eg modprobe snd-hda-intel to load the intel driver-- I am not saying
that is the right one for you, it is jus

Of course it could be that some other program is trying ( and failing) to get
a hold of the sound card at that time but disturbing the system in theprocess.
So to be clear you have some external device (radio, amplifier, whatever)
feeding and audio signal to your sound card. YOu have a program whic
