[Discuss-gnuradio] How to specify Audio Source device_name?
https://discuss-gnuradio.gnu.narkive.com/t7qCKNkO/how-to-specify-audio-source-device-name

After unsuccessfully trying several other ways to run GNUradio, I downloaded ubuntu-14.04.5-desktop-amd64-gnuradio-3.7.10.1.iso and am
Audio Sink appears to be dropping samples : GNURadio
https://www.reddit.com/r/GNURadio/comments/93qqbx/audio_sink_appears_to_be_dropping_samples/
To me, it sounds like the audio sink block is dropping large chunks of samples. To demonstrate this problem, I cut a small snippet of a song I like, and saved it as a 44.1 kHz, 16-bit PCM .wav file. The same file was imported into GRC with a Wav File Source block, and piped directly into an audio sink, all at 44.1 kHz, and the output was recorded.
