Hey there dear community,
I have been struggling with getting a Raspberry 3b+ and microphone setup to run for a few days now, interestingly getting the same error on both projects simultaneously even though they run on different operating systems. I tried both with a seeed respeaker 6mic array and with a Logitech USB-Mic to record via aplay/arecord and get the above error
ALSA Error: ALSA lib pcm_hw.c:1713:(_snd_pcm_hw_open) Invalid value for card Playback open error: -2, No such file or directory
even though I've got all the drivers, specified the correct card and device in the asound.conf, checked if alsa-utils are installed...
Any idea where I could look? xx de

1You "specified the correct card"? What is the correct card? How do you know that? – CL. – 2019-08-13T15:33:53.920
I looked up via aplay -l and arecord -l what card and device numbers alsa assigned the speakers and microphone, and used those in my asound.conf, like so:
pcm.!default { type asym playback.pcm { type plug slave.pcm "hw:0" } capture.pcm { type plug slave.pcm "hw:1" } }
which some users on the forums said solved this problem for them – de-recode – 2019-08-14T13:22:21.760
Please show the output of
