Hello, i am using buster/sid with kernel 4.18.x and espeak. I have also tested to use my old apollo ii connected with an usb-to- serial-adapter with a ftdi-chip. modprobe speakup-apollo dev:/dev/ttyUSB0 load the modul, but the synthesizer will not speak. If i cat a string to /dev/ttyUSB0 the apollo II will speak. The volume ist not "0" and in sys/accessibility/speakup/synth i found "apollo". What can i do? Thanks for your help.
