April Fool day again? okay, sorry, I figured from this reaction, that I asked something completely stupid so I checked again, and found there seem to be some software-only controlled devices, but like huge, expensive, professional matrix mixers, like this one: https://www.tascam.eu/en/mx-8a or are ...

Does anything like this exist, or has any company done any experiments in this? like, AI being an external box with all the inputs, preamps etc, but NO knobs at all with all the controlling done from the PC over the USB this would open limitless possibilities - such as PRESETS for everything - i.e. ...

Update: recording to mp3: arecord -c 4 -f S32_LE -r44100 -t raw | sox -t raw -c 4 -r 44100 -b 32 -e signed - -t raw - remix 1,3 1,4 | lame -r -s 44.1 --bitwidth 32 -b 192 - /path/to/file.mp3 the lengthy sox command - to mix to 2 channels, b/c lame doesn't work with 4 (for wav arecord is enough) 1,3 ...

tried the jack_mixer and hooray, it works without delay! Just need to figure out how to configure this or similar tool to work by default and in CLI and also route all direct ALSA output (e.g. from browsers) through JACK probably by this: https://alsa.opensrc.org/Jack_and_Loopback_device_as_Alsa-to-...

Does JACK have its own master volume control? Or you just use the mechanical knob too?
Thanks

What has happened is that the ALSA developers haven't implemented any control of the hardware. yes, that's what I suspect I tried out a Behringer 404 which had controls in alsamixer I noticed people reporting that, but since Tascam otherwise works excellently, I decided it's better to try to help A...

softvol works with the asound.conf below
but with big (close to 1 second) delay

-- S32_LE -- This is a 32 bit integer format. There's no point in using that as your hardware will be 24 bit. 32 bit float is often used inside a computer but generally software takes care of formats. Hardware uses 24 bit signed integer. thank you, I just noticed that default (16) didn't work and s...

Thinking about the question in the subject: it actually makes some sense that a card that has a physical control of the master volume does not expose programmatic one to the computer. because, unless it turns the knob automatically when volume is changed LOL, the knob position doesn't determine the ...

mplayer works with sample size set to 32 bit i.e. by adding this to /etc/mplayer/mplayer.conf: af=format=s32ne UPDATE: similarly, arecord works with these parameters: -c 4 -f S32_LE And records all 4 inputs. I suspect I should be able to set the format (32 bit sample size) in asound.conf, instead o...

one thing actually did change with update to the latest kernel:
now alsamixer with brutal honesty tells me "This device does not have any controls" (:

upgrading to Kernel 5.17.8 didn't change a thing I'll check if it is any different in Reaper on Windows and update here direct monitoring feature makes the latency problem almost irrelevant in many scenarios - almost, b/c you have to turn the knob between monitoring and playback each time... or keep...

another big problem is latency this is pretty unexpected, I've never experienced latency issues on Linux even with built-in HDA INTEL card but I've read on this forum that USB Audio drivers improved with Kernel version 5.14 so will report after an upgrade (I'm on 4.9.0-12-amd64 atm) UPDATE: lowering...

Hi! I just bought used TASCAM US4x4 It just works - and that is great. There're some issues: - some cracking noize during CPU / IO intensive tasks running on PC - a glitch when first used in every session (it's like it needs a second to warm up or something) - low levels from microphone inputs? (hav...
