Hi, all
My USRP is on delievering, so I try to do someting with the sound card.
Unfortunately, the integrated AC97 sound card of my pc seem to not work properly as source.
I connect a mp3 player with the line-in port of sound card with an audio wire.
In a script, the sound card is set to source and connected to a file sink, so the sampled raw audio is written to a file.
In another script, the raw audio file is set to the source and replayed by the sound card as sink.
But, I hear nothing from my sound card.
The dialtone.py can work making the sound properly, so the sound card as sink is ok.
