Subject: Logitech Z10 USB speakers need a volume change before audio works
Date: Thu, 25 Nov 2021 12:04:41 +0100	[thread overview]
Message-ID: <cf7dd2f0-512c-1b8c-efb1-53f79ddfb41e@redhat.com> (raw)

Hi,

I've a set of Logitech Z10 USB speakers, which act as a USB soundcard.

They have this weird glitch where after turning off my PC (and their
power-supply as well) and then turning things back on, they are silent
until I change the PCM volume control for the speakers inside
alsa-mixer.

It seems like they need some "set-volume" command to be send over the
USB bus to unmute them when initially powered-up / turned on.

Is their some existing usb-audio quirk which I can try to work around this?

Regards,

Hans
