alsa/USB problem.
Posted: Tue Aug 20, 2019 10:14 am
I have an 1818VSL I use as a soundcard.
It worked flawlessly until recently.
I assume an update broke alsa and it is now malconfigured.
For some reason alsa or usb cannot set the 1818vsl up at 48000Hz. Why it tries to do that I dont know as the 1818VSL works at 44100kHz.
The logs show the following error,
[ 9384.412469] usb 1-1.1: USB disconnect, device number 45
[ 9388.014082] usb 1-1.1: new high-speed USB device number 46 using ehci-pci
[ 9388.197230] usb 1-1.1: New USB device found, idVendor=194f, idProduct=0103, bcdDevice= 1.07
[ 9388.197233] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ 9389.020308] usb 1-1.1: USB disconnect, device number 46
So how do I set Alsa (which I suppose creates this error) to rather set the 1818 up at the correct 44100Hz ?
I cannot fi9gure it out. Where do I configure that ?
This question I managed to solve myself. I changed
defaults.pcm.dmix.rate 44100
in alsa.conf and it now tries to start the device at 44100, but it still cannot locate it.
Error is now

[ 642.565893] usb 1-1.1: New USB device found, idVendor=194f, idProduct=0103, bcdDevice= 1.07
But problem remains the same.
So what is going on here that alsa cycles through USB devices 1-127 and then gets the audiobox on the next round.
