The system is on a multiboot pc with a linux mint 19 install using xfce. On that setup, the card is working without problems...

make sure the usb sound driver is set correctly as second device

$ cat /etc/modprobe.d/alsa-base.conf options snd_hda_intel index=0 options snd-usb-audio index=1

my experience shows that some devices get stuck if you suspend or hibernate the other OS (windows)

Thanks,

I tried that, it still doesn't make a difference. Alsamixer on the other hand lets me select the correct device and combined with other alsa info it tells me that alsa does not seem to be the problem here. Kmix just doesn't want to show me the usb device somehow. This audio device (roland rubix) does not have any controls but even that does not stop mint linux from using it anyway. Maybe this usb audio device needs a special alsa configuration that ubuntu provides, but debian/devuan do not? I don't know.

Regards,

Rody

Is tde even capable of using usb cards?

don't use USB sound card, but have a USB webcam with mic. arecord -l **** List of CAPTURE Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: CX20642 Analog [CX20642 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 2: CX20642 Alt Analog [CX20642 Alt Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Webcam [Philips SPC 1000NC Webcam], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0

you can try

pavucontrol

(debian package has same name)

IIRC, pavucontrol is for PulseAudio, whille OP specified they were using pipewire, I think.

Sorry, I missed this and wanted to ask if pipewire is installed. I don't understand why someone would need pipewire. It is always the same loop. Someone starts a project, it's getting adopted while still not fully working and when it starts working (I mean PA) there is a new project that is not fully working.

The question now is - does it work without pipewire?

Just to clarify: I tried installing pipewire to see if it makes any difference. Pipewire is installed but according to ps aux, it's not running. So a dead end there. If I can do it without pulse or pipewire, I will by default.

The current situation is however that kmix won't allow me to choose the rubix usb audio (because it isn't listed there). Mixxx on the other hand DOES use the rubix usb card/box, just like alsamixer is able to see the rubix while kmix does not.

As suggested by E. Liddell, it's possible the Nvidia hdmi audio is acting up, however I've only had such problems on MS Win systems, not on linux so far.

If installing pulse could solve this problem, I could try that. The fact is that the linux mint systems that work without problems with this rubix usb box also use pulse.

This brings another question: why do people - who want a working system, not a test system - install beta grade software when there is something working available (and then complain)?

I don't oppose Wayland or pipewire (as examples), but I'll stick to X and PulseAudio (or alsa) until it's really ready (at least on systems I want to work).

There is a tendency to believe that newer is better that most of us here don't share, otherwise we probably would not be using TDE.

KMix is reading the system devices (AFAIK), so it must be something down the system path that is preventing kmix to list the device It could be also that a patch is needed in kmix for some reason, but we do not have any details.

And those details seem to be so well hidden from us users that we have NDI how/what to troubleshoot when it doesn't work.  Why the secrecy?  straces output is so copious that many can't find (or recognize) the error when we do use it. Please, give us the tools.

Hi Gene, I'm glad to see you here again, hopefully still in good health, respectively good for your age.

And I wish the same for you. Although I don't recall, if its even been told, the diff in the length of our trails thru this thing called time.

I think I'm doing fairly good although long term health problem abound, as they do for most at my age of 90. Sugar=heart attacks and pacemakers, and back damage dating back to my 20's are the main problems.  My 3rd squeeze, a school teacher, I had for 31yrs passed nearly 5 years ago so I'm sick of my own cooking. My machining is more wood than metal these days and I discovered 3d printers about 7 years ago, so have rebuilt some of them to be 10x faster and much more capable of hi temp plastics than OOTB.  I design stuff in OpenSCAD for them. Out of the 11 kids I either married or fathered, I still have 4 boys, 3 are well established, the rest were CP or MD which cuts life short.  MD children made it to about 30. I made 2 girls that have passed from the big C.  Dee left me her 403 so money isn't a problem. Real Estate is paid in full 20+ years ago.

Whats going on with you?  All good I hope.

Cheers, Gene Heskett, CET.

Can you answer two questions

1. is the USB snd card plugged in when you boot into TDE? (and windows

or whatever other system was not hibernated)

2. What is the content of /dev/snd/

for example here it is

# find /dev/snd/ /dev/snd/ /dev/snd/by-id /dev/snd/by-id/usb-Philips_CE_Philips_SPC_1000NC_Webcam-02 /dev/snd/by-path /dev/snd/by-path/pci-0000:00:1a.0-usb-0:1.5:1.2 /dev/snd/by-path/pci-0000:00:1b.0 /dev/snd/controlC1 /dev/snd/pcmC1D0c /dev/snd/controlC0 /dev/snd/hwC0D3 /dev/snd/hwC0D2 /dev/snd/pcmC0D8p /dev/snd/pcmC0D7p /dev/snd/pcmC0D3p /dev/snd/pcmC0D2c /dev/snd/pcmC0D0c /dev/snd/pcmC0D0p /dev/snd/seq /dev/snd/timer

Note 1. is very important. Currently kmix does not track changes in sound cards. So if the usb card is not present when kmix starts, it will not notice it afterwards. You need to quit kmix and start it again manually.
