pageturner

Hallo programmer, first , I very appreciate you for this outstanding Pagrturner code. As I am a rookie to learn LInux, I came cross a problem about the "-audioin test.pcm" command. My hardware is as following description: Ubuntu 14.04 OS 32-bit, 2.4GHz When I run "pt -audioout test.pcm" in Ubuntu environment, there is a series of warning info: -- allen@ubuntu:~/pageturner$ pt -audioout test00.pcm [pt] Version 6. ^C[pt] Caught SIGINT.

So I assume that the "capture" and "playback" of the alsa are well exceuted. ANd it also imply that maybe there are some parameters in Code which has been set to be a conflict to the Ubuntu default setting. Meanwhile, I have no more idea goes to this point. In addition, when I run the "pt -audionin test.pcm", there is more or less the similar warning info with the pervious. However, when I play the pcm file by '-audioin', there is a glitch which makes the voise uncontinue. In contrast, this pcm file could be well played by aplay. -- allen@ubuntu:~/pageturner$ pt -audioin test22.pcm [pt] Version 6.
