Hi,

I am getting the exactly same errors
here, while porting from KDE3.5 to KDE4.

I want either subscribe to this topic and supply additional peaces of 
information:
1) While espeak produces these errors when run from command line, when it is 
selected as backend for speach dispatcher in KDE environment notifications 
sounds normally (e.g. speaking current time).

2) As seen from above quotes, the first checking (lines 926 and 1144) is done 
once (resp. thrice) when espeak starts, while wave_open_sound > Pa_OpenStream 
: err=-9996 (Invalid device) is produced each time new text is supplied (even 
if empty line entered). I tested this running espeak w/o parameters and 
pushing enter several times.

3) Same behavior for unprivileged user and root running espeak.

I am ready and willing to test non-source/packages intrusive experiments 
should you supply guidelines. I know my HW configuration well and can supply 
needed information upon request.

I am using 6ch repro set, relevant lspci part is as follows:
