Hi Geof, thank you for your suggestions.
Here is some more information from my Windows 7 running gnuradio binaries 3.7.10.1 1) When I use a simple wav file source with audio sink and without setting the "Device Name" entry I get the following output: INFO: Audio sink arch: windows gr::pagesize: no info; setting pagesize = 4096 aOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaO I can hear the sound but it is not coming out at the right speed/etc regardless of what sample rate I choose. So I tried the second method that Geof suggested: entering explicitly the device ID and/or the string representing the device's name. 2) Following Geof's advice I went to the "Device Manager" and the "Sounds, video and game controllers" section and I see a device "High Definition Audio Device". I clink on the "Details" tab and under the Property "device description" i see "High Definition Audio Device", so this is what I put as the string under the "Device Name" property of the audio sink. The output then is: INFO: Audio sink arch: windows INFO: Warning: waveOut device 'High Definition Audio Device' was not found, defaulting to WAVE_MAPPER gr::pagesize: no info; setting pagesize = 4096 aOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaOaO aOaOaOaOaOaOaOaOaOa aOaOaOaOaOaOaOaOaOaO And the sound is the same as above. So my question is the following: How exactly can I find in the control panel the name of my audio device? Clearly the one I used ("High Definition Audio Device") was not found... Can it be that the problem is with the "wav file source" block and not with the audio sink block?
