Focusrite Scarlett 6i6 1st Gen No Sound

Hello all,

I am a total FreeBSD newbie so please be understanding. I discovered this post https://forums.freebsd.org/threads/focusrite-scarlett-solo-no-sound.73174/ which shows other folks got sound working on their FreeBSD systems for similar Focusrite Scarlett Solo USB audio interface.

I am assuming my Focusrite Scarlett 6i6 1st Gen cannot be that different from other similar Focusrite Scarlett USB audio interfaces.
I cannot tell --
  • if my Scarlett 6i6 1st Gen USB audio interface is not compatible with the FreeBSD USB Audio driver
  • (or) because I may be missing to install some other pkg packages to make it work.
Questions
  1. Does anyone else have a Focusrite Scarlett 6i6 1st Gen (or similar USB audio interface model) working with FreeBSD 13.1? If so, how? Can you please kindly tell me how you configured it?
  2. If you are using any other Focusrite Scarlett USB audio interface model that is known/proven to be compatible with FreeBSD, please let me know so I can go buy and replace mine if I cannot get this Scarlett 6i6 1st Gen to work.

  • I am using vanilla FreeBSD 13.1 with Generic kernel and my CPU.
  • Code: 
    # uname -v
FreeBSD 13.1-RELEASE releng/13.1-n250148-fc952ac2212 GENERIC
  • This is my /etc/rc.conf.
    Code: 
    # cat /etc/rc.conf

keymap="us.kbd"
ifconfig_em0="DHCP"
sshd_enable="YES"
ntpdate_enable="YES"
powerd_enable="YES"
# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="AUTO"
zfs_enable="YES"
dbus_enable="YES"
gdm_enable="YES"
gnome_enable="YES"
kld_list="nvidia-modeset"
  • This is my /boot/loader.conf.
    Code: 
    kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"
cryptodev_load="YES"
zfs_load="YES"
kern.vty=vt
  • Yes, I have read and referenced the FreeBSD Handbook Section 8.2 Setting Up the Sound Card section. After researching more in the forums, I am aware that the Sound module/driver is already included in the Generic Kernel. That is why I do not have snd_driver.
  • This shows the snd_uaudio driver has been automatically loaded by the Generic kernel for my Scarlett 6i6 1st Gen.

  • However, Gnome Sound settings doesn't list my Scarlett 6i6 1st Gen USB Audio Interface. It is only showing my Nvidia card's HDMI stuff.

Is there anything else I can do to diagnose and troubleshoot this?
Thank you for your time!

I have also a focuswrite which doesn't work. Too bad.
I think software needs reverse engineering. As the hardware don't follow "standards".
The "mixer" is "confused".

PS: With Linux/alsa it works.

So my best guess is try Linux or Windows.

Or develop a driver for FreeBSD :)

The simple very cheap focuswrite with "few-channels" might work.
 
I am surprised that it even recognized all the channels. My MixPre 10T is stuck with 2 channels in and out each under FreeBSD and Linux although it has 10.

I have a 2i2 that I didn't try under FreeBSD yet. Will do so shortly (this week or so).

I know that Scarlett publishes "drivers" which are additional control software on top of the actual drivers it doesn't need (due to USB audio compliance). I would guess that some routing internal to the device is controlled by it and that without that control you don't get some required things connected. In the case of the 2i2 I can ignore that additional software under macOS and Linux, though.

If you want a more though test in the meantime, please try to run audio/jack's jackd on your interface. Who knows what GNOME's mixer is trying to do there. jackd prints useful stuff.

If i remember a 2i2 might work due to the low number of channels.
Click to expand...

I just tested it under 14-current, it works fine, input and output.

The number of channels itself should not do any damage to FreeBSD's ability to drive the big one. As I said, I suspect that some Scarlett software sends special commands when you install their "driver" package, for example for routing. But that doesn't explain why GNOME doesn't show it although it clearly establishes an audio device in the system.

The jackd test is the next thing to try for stun
 
Thank you both. I will try these and come back to comment whether it works.
  1. First, I will try playing around with jackd.
  2. Afterwards, I will try using FreeBSD 14 to see if it works.
  3. If neither works, I will go buy a Scarlett 2i2 3rd Gen model and see if it works.
 
I read somwhere an a forum that Scarlett uses propriaritery commands which don't follow the Standards.
When the number of channels is eg 2 , they get correctly detected by the software.
 
  1. ❌ I tried running QjackCtl with oss driver for audio/jackd. I didn't try ALSA driver as I didn't want to waste too much time figuring out how it works as I couldn't find a good clear and concise documentation for FreeBSD.
  2. ❌ I wiped and installed FreeBSD 14-CURRENT and it couldn't detect my Scarlett 6i6 1st Gen either.
  3. ✅ I finally went and bought a Scarlett 2i2 3rd Gen and went back to FreeBSD 13.1-RELEASE with Gnome. It works immediately ? and shows up in Gnome Sound Settings UI after sysctl hw.snd.default_unit=5 setting change as Alain De Vos said earlier that fewer number of channels will most likely work.
Thank you both for your help ?‍♂️ ?
