Boss RC-300 Audio interface appears but Jack does not work with it

What other apps and distros do you use to round out your studio?

Boss RC-300 Audio interface appears but Jack does not work with it

Post by zugzug »

Hey guys,

I got a new RC-300 Loop Station...Nice Looper!
But now I want to you use the Audio-interface of it and have some problems. If I do the following:
cat /proc/asound/cards /proc/asound/module
0 [VirMIDI ]: VirMIDI - VirMIDI
Virtual MIDI Card 1
1 [Loopback ]: Loopback - Loopback
Loopback 1
2 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xf7b14000 irq 36
3 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7b10000 irq 35
4 [RC300 ]: USB-Audio - RC-300
BOSS RC-300 at usb-0000:00:14.0-2, high speed


The RC300 appears in Jack. But I can't get it as Audio-Source for Jack. Everytime when I select the RC300 as input jack crashes.
And also in my Patch-Bay the Audio Source/Sink of the RC300 does not appear....only the Midi is available
I took some screenshots for you in my Attachments, cause of my bad explanations


Maybe my configuration is totally wrong :-)Can somebody help me? I'm actually not a Ubuntu/Linux pro...

Usually for USB set periods, buffer to 3.

Force 16 bit is ticked, is that deliberate?

Also I would set input and output device to none and choose your interface in the device/interface drop down list instead

Hi,

thanks for your help.
Actually I don't think that the Jack configuration is the problem.
I read something about a missing entry @ quirks-table.h but I don't think that this is my problem. Cause when i enter aplay -l my RC-300 is listet:
aplay -l

Code: Select all

Maybe it's the same problem as in this topic....but there is no solution
viewtopic.php?f=4&t=16394&p=76258&hilit ... ace#p76258

now I've found something that could be the reason.

Code: Select all

cat /proc/asound/cards 
 0 [VirMIDI        ]: VirMIDI - VirMIDI
                      Virtual MIDI Card 1
 1 [RC300          ]: USB-Audio - RC-300
                      BOSS RC-300 at usb-0000:00:14.0-1, high speed
 2 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf7b14000 irq 36
 3 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7b10000 irq 35
 4 [Loopback       ]: Loopback - Loopback
                      Loopback 1
In this code, the USB-Adress of RC-300 is usb-0000:00:14.0-1. But in lsusb I have:

Code: Select all

Bus 003 Device 008: ID 0582:0138 Roland Corp. Boss RC-300 (Audio mode)
could this be the reason?
Has anybody an other idea?

Try starting jack from the command line with the default settings and look for relevant info in the terminal output

Code: Select all

jackd -dalsa -dhw:RC300

i have exact same problem and will do whatever troubleshooting is needed to resolve the issue
if the original poster has given up.

Re: Boss RC-300 Audio interface appears but Jack does not work with it

Post by digikwondo »

so spent a bit more time investigating this, but first i want to admit im no real programmer or linux driver guru.
but i think i have found something. to keep things simple my aim is to simple stream from the RC-300 over
usb into my old trusty (and beer smelling) laptop where i record through ardour or audacity.

but my first test does not use jack at all. as per bellow screenshots just simply tried to rout the sound from my rc300 over usb and out into my connected creative bluetooth speakers.

i have tried both the analog and digital Boss options but no sound through my speakers.

digging arround in the /proc folder i found this

Code: Select all

$cat /proc/asound/card1/stream0 

BOSS RC-300 at usb-0000:00:1d.7-4, high speed : USB Audio

Playback:
  Status: Stop
  Interface 1
    Altset 1
    Format: S32_LE
    Channels: 2
    Endpoint: 13 OUT (ASYNC)
    Rates: 44100
    Data packet interval: 125 us

Capture:
  Status: Stop
  Interface 2
    Altset 1
    Format: S32_LE
    Channels: 2
    Endpoint: 14 IN (ASYNC)
    Rates: 44100
    Data packet interval: 125 us


could the "Status: stop" be the cause here ?
bellow is some more info

i have never sued the windows driver for this thing but could it be that these is some
kind of software "switch" built into it that enables and disables (open/closes) the stream ports "pcm0p" and "pcm0c".


as im not an expert in any way i would appreciate if someone could tell me if im totaly wrong here.
as i dont want to go down the wrong rabbit hole :)
