Re: [SOLVED] Error when running espeak

Redirect stderr to /dev/null if it's just about hiding the messages

espeak 2>/dev/null

Thanks,

Is it safe to ignore the errors thought?

Re: [SOLVED] Error when running espeak

Yes, espeak just tries accessing the sound card through any means known to it and ultimately settles on what I suspect to be a pulseaudio backend or so. I'd say that it just tries that much is technically a strangeness in espeak and it should be configurable, but a cursory googler doesn't look like you can manually specify the audio backends to try
