Hiya, I need some support for optimal configuration for the USB Audio Interface "Focusrite Scarlett 2i2 (2nd gen)"
I want to put these options for this specific USB interface only:
format S24_LE
channels 2
rate 192000
Right now my ~/.asoundrc is empty and /etc/asound.conf contains the default config.
This is the hardware info:
# cat /proc/asound/cards
3 [USB ]: USB-Audio - Scarlett 2i2 USB
Focusrite Scarlett 2i2 USB at usb-0000:00:1d.7-5, high speed
# aplay -l
card 3: USB [Scarlett 2i2 USB], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0
What settings do I need to configure? Is there some expert or audiophile here? :-)

This is my /etc/asound.conf
# Use PulseAudio by default
pcm.!default {
type pulse
fallback "sysdefault"
hint {
show on
description "Default ALSA Output (currently PulseAudio Sound Server)"
}
}
ctl.!default {
type pulse
fallback "sysdefault"
}
# vim:set ft=alsaconf:
defaults.pcm.rate_converter "speexrate_best"
In /etc/pulse/daemon.conf I have already changed to this;
; default-sample-format = s24le
; default-sample-rate = 192000
; alternate-sample-rate = 192000
But it have no effect when I run speaker-test, I get Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels

Hey,
just registered to help you out - to get the stuff in /etc/pulse/daemon.conf working, you need to remove the ";" in front of the values you changed.
I had the same problem today as i wanted to get my Dragonfly working
You also might change "resample-method" to "speex-float-10" if you have the CPU to spare.
I'm currently using "speex-float-5" - if i change it to 10 my system is at 100% all the time.
Hope this helps.

Thanks for your kind response. Well I hope these settings are working now. My pc is a 3ghz quad core, 8gb ram. When I put speex-float-10 the sound is gibberish, but speex-float-5 works nice. I got Rokit 5 G3 with Scarlett 2i2(2nd gen) and the sound is so crystal clear now.
If you got any tips, tweaks or improvements let me know. This is my config now in /etc/pulse/daemon.conf
high-priority = yes
nice-level = -15
realtime-scheduling = yes
realtime-priority = 5
resample-method = speex-float-5
default-sample-format = s24le
default-sample-rate = 192000
default-sample-channels = 2
default-channel-map = front-left,front-right
default-fragments = 5
default-fragment-size-msec = 1
deferred-volume-extra-delay-usec = 0
rlimit-fsize = -1
rlimit-data = -1
rlimit-stack = -1
rlimit-core = -1
rlimit-as = -1
rlimit-rss = -1
rlimit-nproc = -1
rlimit-nofile = 256
rlimit-memlock = -1
rlimit-locks = -1
rlimit-sigpending = -1
rlimit-msgqueue = -1
rlimit-nice = 31
rlimit-rtprio = 9
rlimit-rttime = 200000

Settings looking good.
You can check if everything runs as configured with:
pacmd list-sinks | grep sample

I get:
$ pacmd list-sinks | grep sample
sample spec: s16le 2ch 48000Hz
sample spec: s32le 2ch 192000Hz
sample spec: s16le 2ch 48000Hz
sample spec: s32le 2ch 192000Hz
