Python - No Beep

[s.fox]

Hello,

I have been trying to learn more python and have come across a problem getting a system beep.

I did some searching and everything I have seen indicates that print '\a' will work. Can someone please assist?

Below is my simple little script. It is a timer script which I am trying to get to beep when time up and also display a message.



#!/usr/bin/python
import time
import threading

msg = 'Input Time In Minutes: '
uin = raw_input(msg).strip()
intSecAsMin= int(uin) * 60

class Timer(threading.Thread):
def __init__(self, seconds):
self.runTime = seconds
threading.Thread.__init__(self)
def run(self):
time.sleep(self.runTime)
print '\a'
print "Time Up!"

t = Timer(intSecAsMin)
t.start()
Any help would be great, thank you :D

Edit:

I have also tried chr(7) and that did not work either. I can also confirm that the package beep is installed


Package beep-1.2.2-5.fc12.i686 already installed and latest version-Silver Fox

The beep package is not relevant to what you're doing, although supposedly you could use it as an alternative to what you're doing. (I haven't used it, just read the description.)

Beeping is a function of the terminal. Often it's mapped to a visual "beep" (flash) instead of audible. Right now, using "echo -e '\a'" in Gnome Terminal as a test under Ubuntu 8.04, I'm not seeing or hearing anything, even though "Terminal Bell" is checked in the profile. So yeah.

Hmm... xterm does nothing, either. Heck, I don't know if I even have an old-style PC speaker device on this machine (Asus Eee PC 900A). Maybe they're just trying to beep something that's not there.

Edit: I just tested on my 9.10 system, and I get a barely-visible flash of the title bar.

Hello,

Thank you for responding to my query. :)

Thank you for informing me of this, I wasn't totally sure. I just wanted to rule it out :)

I too get that result.

Thats an interesting point. Do you mean that our machines may be lacking the hardware to beep in this manner?

Once again thank you for your input on what I am trying to achieve,

Make sure the pcspkr module is loaded. It is not loaded by default in Ubuntu, maybe Fedora doesn't load it either.

Hello,

Thank you for replying to my thread.


EDIT: never mind, you're on Fedora..

The code was initially written on Fedora and didn't work. I have since tested it on Ubuntu 9.10 and #!Crunchbang Linux 9.04 and had the same result. Instead of beeping all I get is an empty line in terminal. :(

That sounds like it could be the cause of the problem I am experiencing. I just did a search in synaptic for pcspkr and could not find it listed. I am pretty green at python but I thought that was how you would install the module. Am I incorrect?

Thanks again for your time,

Edit: Fixed a small typo in the original code. Somehow during copy and paste I missed off the closing ) on t.start

Sorry, I should've been more specific. :p pcspkr is the kernel module which acts as a driver for the speaker-thingy inside PCs. It is blacklisted in Ubuntu by default:


# ugly and loud noise, getting on everyone's nerves; this should be done by a
# nice pulseaudio bing (Ubuntu: #77010)
blacklist pcspkr


Just do a


sudo modprobe pcspkr

and try again. You might also want to try that in a virtual console instead of an xterm.

Oh, I see :D. Thank you for clearing that up.


sudo modprobe pcspkr

Tried that and ran in virtual console, still no joy :(

Thank you for your help :)

I too have tested this and it does not seem to work anymore. The pcspkr module is blacklisted by default in /etc/modprobe.d/blacklist.conf - commenting that line does not seem to resolve the issue though.

I'd use pygame to load a basic wav file or something.

I was thinking about doing that, but would be nice to get the beep working :)
