@Mykle1 Sorry to be bothering you again, decided to switch to my pi4b to see how it performs, and now the usb camera I had working on the pi3b+ will not work now, arecord -l lists it as card 2 device 0 and it still says error. Im at a lost npm start dev shows no errors and if I take the same config over to the 3b+ with the proper mapping it works fine
pi@MagicMirror:~ $ arecord test.wav ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM input arecord: main:828: audio open error: No such file or directory -
@snikolaidis on you pi3 you have a file ~/.asoundrc
did u build one on pi4 ? with the right info? -
@sdetweil said in Hello-Lucy:
~/.asoundrc
Pi3 file doesnt exist - mic shows error but works
pi4 file exists - mic shows error still doesn’t work -
@sdetweil also weirdly enough

@snikolaidis before we get to MM with lucy, arecord must work
arecord: set_params:1339: Sample format non available Available formats: - S16_LEyes, it didn’t record cause it can’t do the default

@snikolaidis and aplay test.wav do you hear what you said?
-
@sdetweil >if i specify the USB camera it works,
ok, so, how do you update lucy to use the usb camera config ?
-
@sdetweil
yes on both i hear what i said and changing the microphone line in config is all i’ve ever done to get it working, flash raspbian -> install MM and modules -> run arecord -l and change the mic config line to what my pi reflectsPi4b

@sdetweil i specified the mic in ~.asoundrc so now arecord goes directly to the usb mic but still throws the format code, lucy still wont pick it up tho
pcm.!default { type asym playback.pcm { type plug slave.pcm "output" } capture.pcm "hw:2,0" } pcm.output { type hw card 1 } ctl.!default { type hw card 1 } -
mine is
pcm.!default { type hw card 0 } ctl.!default { type hw card 1 }so I would guess yours would be
pcm.!default { type hw card 2 } ctl.!default { type hw card 1 } -
@sdetweil yeah still not working with lucy even though arecord works, would it have anything to do with that i went beta with the pi4?
-
-
@sdetweil the beta firmware & bootloader that lets you boot from usb
sudo apt update sudo apt full-upgrade Sudo nano /etc/default/rpi-eeprom-update sudo rpi-eeprom-update -d -f /lib/firmware/raspberrypi/bootloader/beta/pieeprom-2020-05-27.bin -
@snikolaidis oh… that won’t affect sound
-
@sdetweil Sorry trying to think of anything possible
-
@snikolaidis said in Hello-Lucy:
on another note, i guess i said too many unkown commands or somethings and a list of all the commands possible popped up and wont go away, any thoughts other than rebooting
Oh, did you mean commands to Lucy? The Command List appeared? You can say “Hide Help” or “Close Help”.
-
Thank you @sdetweil for doing the troubleshooting on this one. :thumbsup:

@snikolaidis Did you ever figure this out? I have a pi4 and have a logitech webcam c920 … it shows as card 2 and should be 2,0 … I can record and play back in arecord Everything from what I can see works fine except when in MM Lucy talks and then when waiting for command her icon goes to ERROR.
I have gotten this to work with a sunfounder usb mic (just a crappy mic) and I was hoping the lag would be better using the webcam mic. (waiting for my new 3.5 jack microphone which should help the lag).
In any case I just do not know why Lucy doesn’t pick up the webcam mic??
@Mykle1 does it make sense it doesn’t work? -

@Mykle1 does it make sense it doesn’t work?Well I THOUGHT I had the crappy usb microphone working on my RPI 4 but I am wrong …Same issue as with webcam.
I do know I had this working on my RPI3 last night with crappy usb microphone… The only difference I can see is on the RPI3 it put the usb mic on CARD 1 . on the rpi4 no matter what I put in as a usb mic…it puts it as CARD 2 device 0. On the RPI4 I have “headphones” as card1 and HDMI as 0. I get sound out of both hdmi and 3.5 jack (headphones)…Arecord does record using either usb mic I use. For whatever reason Lucy just keeps throwing ERROR when trying to initialize the mic
