They can, but in general, if the USB device has physical controls,
then it has no need for alsa controls (there are no computer
controlable controls in any OS). Many USB audio chipsets (or maybe I
should say cheap chipsets) just do the audio with no controls. I think
there is a complient way of doing controls, but that may not deal with
more complex routing. It seems the thing these days is to make the
audio interface double as a digital mixer to help it actually sell for
the higher price asked. I don't think USB2.0 covers such a use.
Hi,
sorry for writing off-list, but the D* who runs this list banned me
for absolutely no reason, see [1].
I already replied off-list to Tim [2], since he quoted what I've
written at the jack mailing list.
No problem.
Your points brought me "back down to earth".
For some reason I thought ALSA could handle every card.
And that therefore every distro should have some great
ALSA mixer like Qas. All problems solved.
But it's more complicated than that, as you say.
Again, I guess I just feel sad if some user goes away
disappointed. I (and all of us) always try to help people,
even newbies, have a good experience with Linux audio.
With MusE we try to make it friendly but with power behind it.
I want everyone to have a good experience and have fun.
Actually the 18i20 provides potentiometers for the 8 analog input
channels and for 2 of them additionally "pad" switches, but it only
provides output potentiometers for the two headphone outputs and for 2
channels aimed as monitor output, which is quite useless without access
to the hardware IO routing.
The ADAT device I'm using provides input level potentiometers, but no
ouput level control.
The RME HDSPE has got no input level control at all and some
microphones, e.g. the Brauner VM1 have their own output "pad" switch.
Nobody who has got a halfway professional workflow needs a level control
at all stages.
I'm anyway using the Behringer replica of the mixing console Len does
use. Btw. a friend owns an old revision of the Mackie. I didn't compare
the audio quality directly, but at least I can say two thing. The
Mackie is way noisier than the Behringer, but the Mackie provides more
space between the potentiometers, so it's more pleasant to handle and
easier to clean. I do understand that people wish to get rid of a
mixing console. A friend likes to lend me a huge mixer, better than the
small Mackie, Behringer and Co. mixing consoles, but I don't have the
room for a huge mixer.
Yes, I was saying that I have a mixer sitting in a box,
but my relatively simpler needs are such that my ten-channel
delta1010 card pretty much does all of that for me.
I should put an analog compressor/limiter ahead of the card,
but I'm so used to playing/recording without it.
T.

Ralf

Hi,
for some audio devices even the revision could make a difference.
The claims regarding the Scarlett 18i20, see
https://lists.linuxaudio.org/archives/linux-audio-user/2019-March/111865.html
are incorrect for the 2nd generation. IOW the 18i20 that is actually
sold and works up to 192kHz isn't supported as described. It might work
for second-hand 18i20 of the 1st generation that supports up to 96kHz.
Regards,
Ralf
