Re: [Discuss-gnuradio] Dial tone under GNU Radio Companion fails

[Josh Blum]

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?

Maybe the underlying implementation of the alsa sink changed from 3.2.2 
to next? Anybody aware of this?

Take a look at the docs in the Audio sink block, I think there is a note 
to enable the resampler, or just pick a sample rate that your sound card 
agrees with.
