USB Speaker doesn't appear unless plugged in and out

[MarkMB1]

Hi i am just wondering is there a way to get the raspberry pi to detect the usb speaker on boot. If the pi is rebooted and the speaker is plugged it, it will not work or even appear until it is plugged out and back in again.

Thanks

Try disabling the Pi's internal sound card.

Code: Select all

sudo mousepad /boot/config.txt

Add a # before dtparam=audio=on, and below it add dtparam=audio=off.

Like this:

Code: Select all

# Enable audio (loads snd_bcm2835)
#dtparam=audio=on
dtparam=audio=off

Save the file (Ctrl+S), then reboot. See if that work. If not, what does the command lsusb say?

I just tried that and it didn't work when i execute the command lsusb the USB speaker doesn't appear

Code: Select all

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

However when its plugged out and in again it appears

Code: Select all

Bus 001 Device 002: ID 1908:2070 GEMBIRD

What Raspberry Pi model are you using?

Raspberry pi zero w

It appears the Pi zero can shut off power to its usb ports.

Try running this command when the usb speaker is plugged in but not recognized:

Code: Select all

echo 0 > /sys/devices/platform/soc/20980000.usb/buspower
