I agree, but I was talking about the documentation, not about the quality of the software. Check the main documentation site https://alsa-project.org/wiki/Documentation The first section contains 4 items, the second of which is just a title (no link) and the 3rd is a dead link...

I have a micro which connects to an interface via a XLR cable (it works; I can hear sound through headphones connected with the direct monitor output in the interface); the interface gets power from the computer via USB (works); the RCA output of the interface connects to the LineIn entry in the card.

The ones for playback, and the ones for capture. (see F4 in alsa mixer). Also see F6 to select the right sound card if you have more than one. If you have more than one input (on that card), make sure you select the right one, You can toggle "capture" with space. Untoggle all of them, and leave on just the one you use for recording.

Both device 0 and device 2 are on the *same* card. I would think an external device as you posted previously would register on the kernel as a separate card. Is dmesg recognising your USB mic when you plug it in? Do you need some additional driver for it? Is there some On/Off button on it you need to turn it on with? > ## arecord -L > null > Discard all samples (playback) or generate zero samples (capture) > default:CARD=PCH > HDA Intel PCH, Generic Analog > Default Audio Device > sysdefault:CARD=PCH > HDA Intel PCH, Generic Analog > Default Audio Device > front:CARD=PCH,DEV=0 > HDA Intel PCH, Generic Analog > Front speakers > usbstream:CARD=PCH > HDA Intel PCH > USB Stream Output Hmm ...

Audio drivers were not as polished as they are today for Linux. Anyway, I remember contacting some dev who asked me to rebuild my kernel with alsa as modules and run 'alsactl init', which would only produce a full output this way. I don't know if this would still be a problem today and anyway you are not experiencing the same bugs I was troubleshooting 15 years ago. So, in the first instance I would look at a USB driver, if needed, from the output in dmesg. lsusb -v would also show any bInterfaceClass 1 Audio bInterfaceSubClass 1 Control Device and any fields showing "Microphone". Finally, have a look under 'cat /proc/bus/input/devices' or similar for any USB devices, to find out what driver it is using. HTH.

Humm... The point is: the interface (Behring) has RCA output, which is connected to the LineIn of the integrated sound card (not an USB card). On the other hand, it also has a USB output, which is used to get Phantom Power (whatever that is), which works (when removed from the USB entry in the computer, the LEDs go off). However: I think the device (Behring) also works as a USB sound card (which I don'y want to use). > > Both device 0 and device 2 are on the *same* card.

The question now is whether the signal on RCA outputs is suitable for a sound card - i'm not sure, but IIRC i've done this before and it worked. I'd be inclined to try setting up the Behring USB though - if its a high end device it will probably sound better.

The MO is STRIX B250F GAMING. I assumed it would be somewhat better than a USB card (and the Behring model I have is not that high end) Anyway, I just build (and modprobe'd) the modules snd-usb-audio and snd-bcd2000, and still no joy: arecord -D usbstream:CARD=PCH -fdat -r 48 test.wav ALSA lib /var/tmp/portage/media-plugins/alsa-plugins-1.2.1/work/alsa-plugins-1.2.1/usb_stream/pcm_usb_stream.c:508:(_snd_pcm_usb_stream_open) Unknown field hint arecord: main:828: audio open error: Invalid argument Jorge ^ permalink raw reply [flat|nested] 21+ messages in thread
