Hi,

before I migrated from Linux real-ti= me pro-audio to Apple for audio and
other artwork, one of my doma= ins was jackd with the alsa backend on
Linux. On FreeBSD your bac= kend is most likely "or else".

i use = it on debian/Linux, it was worked

Most likely I cannot help you with FreeBSD audio, but at least I= can
contribute something related to your request in general, wha= t ever
operating system you are using.

W= hile it's possible to use two audio devices on Linux and probably on
<= div>FreeBSD, too, it requires to sync those audio devices, either by<= div>hardware, for low-end devices it might be possible via SPDIF (prosumer<= /div>
and professional devices provide word clock or the less good ADAT= sync)
or by software resampling.

my USB audiobox with my USB dongle was worked perfectly on debian


Is there a= ny way to sync those two devices by hardware?

If n= ot, google for FreeBSD and audio device sync by resampling software.
<= /blockquote>

with jack and pluseaudio it's work

Related to the COVID-19 pandemi= c I was forced to use Zoom and similar
hells on earth. It was alr= eady a PITA on iPadOS, just for video
conferences without my guit= ars involved, by just using the integrated
audio device.

In a nutshell, if possible use one audio device, don't try= to make two
audio devices a virtual single audio device, since y= ou don't need two or
more construction sites. Use one audio devic= e, one input channel for the
microphone and another channel for t= he guitar. Depending on your audio
device you might need addition= al pre-amps.

i have


Using a wireless audio de= vice makes it way more error prone. If possible
avoid using a wir= eless device. Even if you should be fine with getting
Bluetooth t= o work, the wireless related IRQs affect the whole audio
chain.

no bluetooth headset but reconyze as s= ound card


Try to get a working setup by just using a single non-wireless audio
device, you much likely have enough to struggle with getting Zoom or<= /div>
else to work, so don't make it more complicated by trying to sync= two
audio devices and don't make it extra complicated by using a= wireless
device.

Just my 2 Cents (I'm s= erious, this isn't an April hoax)
Ralf
me too
