Using the mentioned setup (wired USB to the speakerphone, not bluetooth), it works fine when just playing music. But when using it for making (video)calls in Chromium with Web Skype or Facebook Messenger, only the mic works. The speaker buzzes a bit first for a few seconds, and then becomes silent.
Using latest & updated Raspbian.
Any ideas or experience someone could share? Might I need to setup any additional software/drivers to get the speakerphone to work properly?
Thanks in advance for input!
