[BRLTTY] Build brltty with support for espeak-ng

[Tage Johansson]

I ran:

$ sudo ./run-brltty -Lbrltty.log -lspeech,debug


I then moved between two lines in the terminal:

1. [tage at alarm ~]$ bbbbbbbbbbbbbbbbbbbbbbb

2. -bash: bbbbbbbbbbbbbbbbbbbbbbb: command not found


I've cut out a illustrative part of the logfile and pasted it at the 
bottom of this message.


Here's what I think is happening:

1. I start by moving to line 1.

2. Brltty receives my command and autospeaks line 1.

3. The speech request to speak line 1 is enqueued and send to the 
speech-driver.

4. The speech-driver handles the request to line 1.

5. I move to line 2.

6. Brltty receives my command and autospeaks line 2.

7. The speech request to speak line 2 is enqueued and send to the 
speech-driver.

8. The speech-driver starts to handle the request to speak line 2 but hangs.

9. I move to line 1.

10. Brltty receives my command and autospeaks line 1.

11. The request to speak line 1 is enqueued but never send to the 
speech-driver because the request to speak line 2 has not been handled yet.

12. 1.7s later, the speaking of line 1 is finnished.

13. The speech-driver handles the request to speak line 2 done.

14. Brltty sends the request to speak line 1 to the speech-driver.

15. The speech-driver handles the request to speak line 1.

16. The speaking of line 2 gets interrupted and is reported as finnished.

17. 2.6s later, the speaking of line 1 is reported as finnished.


The strange thing here is that the request to speak hangs at step 8 but 
not at step 15. Any ideas what might be wrong?


And here's the log:
