Multilple Sound Cards Setup

[EclecticallySound]

I am newbie looking for some guidence for setting up multilple sound cards on my Linux Box. I hope that I have posted this in the correct forum, appolgies if I have not.

OS - Ubuntu 14.04.1 LTS, (Trusty Tahr), KXStudio Spin – 64 Bit

Hardware - AMD Atholon 64 3200+ 2GHz

Sound Card(s)

Audigy2 - SB Audigy 2 ZS [SB0350] – PCI
Focusrite Scarlett 6i6 Novation EMS - USB
Roland Corp. USB MIDI Interface UM-ONE – USB {Connection to Yamaha MIDI Keyboard}

Code: Select all

$ cat /proc/asound/modules

0 snd_aloop
1 snd_emu10k1
2 snd_usb_audio
3 snd_usb_audio

I have backed up my alsa-base.conf


My question is may I just edit my “/etc/modprobe.d/alsa-base.conf” to make my Scarlett 6i6 USB default, “snd-card-0” with the following:

Code: Select all

alias snd-card-0 snd-usb-audio
alias snd-card-1 snd_emu10k1
alias snd-card-2 snd-usb-audio
alias snd-card-3 snd-virmidi
options snd cards_limit=4
options snd-card-1 snd_emu10k1
options snd-usb-audio index=0,2 vid=0x1235,0x0582 pid=0x8012,012
options snd-virmidi index=3 midi_devs=2

As a newbie I am unclear on wether I may just add that to the end of my alsa-base.conf file or if there are other steps I must do like commenting out certain lines etc, so before I soil the sheets I would greatly appreciate input from anyone with the time and knowledge to guide me in the right direction, thank you kindly in adavnce

Current alsa-base.conf :

Code: Select all

My question is may I just edit my “/etc/modprobe.d/alsa-base.conf” to make my Scarlett 6i6 USB default, “snd-card-0” with the following:

installed: jack-audio-connection-kit-2.9999

Show your SC:

Code: Select all

cat /proc/asound/cards

I put the default SC in

Code: Select all

/etc/modprobe.d/alsa.conf

(*buntu maybe "/etc/modprobe.d/alsa-base.conf")
example for several SC:

Code: Select all

options snd-emu10k1 index=0
options snd-via82xx index=1

or for 2 SC with the same driver:

Code: Select all

options snd-ymfpci index=0
options snd-hda-intel index=1,2

and everything fine now (boot sequence).
German: https://www.gentoo.org/doc/de/alsa-guide.xml <-- Mehrere Soundkarten (multiple SC)
.en: http://gentoo-en.vfose.ru/wiki/ALSA_Mul ... figuration

To storage alsamixer settings use (as root)

Code: Select all

alsactl store

for each SC.

[khz]

installed: jack-audio-connection-kit-2.9999

1. Show your SC:

Code: Select all

cat /proc/asound/cards

edit

Code: Select all

/etc/modprobe.d/alsa.conf

(*buntu maybe "/etc/modprobe.d/alsa-base.conf")
example for several SC, use the output from "/proc/asound/cards":

- different driver:

Code: Select all

    options snd-emu10k1 index=0
    options snd-via82xx index=1

- or for 2 SC with the same driver:

Code: Select all

    options snd-ymfpci index=0
    options snd-hda-intel index=1,2

2. To storage alsamixer settings use (as root)

Code: Select all

alsactl store

for each SC.


3. Default SC for a program (example Firefox):
edit:

Code: Select all

~/.asoundrc

Code: Select all

    defaults.ctl.card 0
    defaults.pcm.card 0
    defaults.timer.card 0

4. Bring your Soundcards together in qjackctl:
A)
Setup >> Options >> [X] Execute script on Startup

Code: Select all

jack_load -i "-d hw:1 -i16 -o16" 9632 audioadapter && jack_bufsize 128 &

hw: you like to bind (hw:0 / ...)
-i <-- your number of SC inputs
-o <-- your number SC outputs
9632 <-- how do you like to name the jackport
jack_bufsize <-- JACK toolkit client to change the JACK buffer size

B)
For Alsa2jack (MIDI):
install:

Code: Select all

a2jmidid

Setup >> Options >> [X] Execute script after Startup

Code: Select all

sleep 5 && a2jmidid -e &

5. Flash & jack

install

Code: Select all

alsa-plugins

edit

Code: Select all

nano .asoundrc

Code: Select all

# convert alsa API over jack API
# use it with
# % aplay foo.wav

# use this as default
pcm.!default {
    type plug
    slave { pcm "jack" }
}

ctl.mixer0 {
    type hw
    card 1
}

# pcm type jack
pcm.jack {
    type jack
    playback_ports {
        0 system:playback_1
        1 system:playback_2
    }
    capture_ports {
        0 system:capture_1
        1 system:capture_2
    }
}

card 1 <-- if you like the "card 1" (or "card 0" ...).
