Re: [Discuss-gnuradio] Dial tone under GNU Radio Companion fails
48000 did the trick. The program now works. Many thanks.

I think initially I was able to get it working using 48000 as the sample rate, so you might try that value.

Re: [Discuss-gnuradio] Dial tone under GNU Radio Companion fails
So, from what I gather, you build and ran 3.2.2 and dial tone worked fine. However, building and running dial done on the next branch gives you the following error? audio_alsa_sink[hw:0,0]: unable to support sampling rate 32000 card requested 44100 instead. Maybe the underlying implementation of the alsa sink changed from 3.2.2 to next? Anybody aware of this?

[Discuss-gnuradio] Dial tone under GNU Radio Companion fails
I have installed GNU radio and UHD as per instruction of Marc Epard (3Aug). I am running UBUNTU 10.04. When running GNU Radio Companion and trying to run the dial tone example I get the following output on the terminal with failure of the program to run. When using the 3.2.2 version of GNU Radio and invoking GRC the program ran fine. I am "GNUbee" and would appreciate help with this problem.
