Hello Pedro, Tvtime doesn't support reading on ALSA devices - this is an issue not specific to the em28xx, but effects pretty much every modern tuner - tvtime was written during a time when capture cards had a line out cable that you would connect to speakers. I've written about the topic at length on the kernellabs.com blog if you want more info. Note that the em28xx provides a PCM *input* device. To get audio, you will typically read on the em28xx PCM device and output to your sound card. To make it work in tvtime, run tvtime, open a separate window, and try the following: arecord -D hw:1,0 -c 2 -r 48000 -f S16_LE | aplay - (assuming that the em28xx board is detected as "1,0" if you run "arecord -l") Devin -- Devin J.
