Hello, I have an Intel D945GTP board with onboard sound, a Intel HDA card which uses the SigmaTel STAC9221 A1 codec. I'm not even sure about what I'm saying. I just tried to digest lscpi, dmidecode and /proc/asound/. The point is that I have no feedback of Mic nor Line input. Input works, and I can record it with arecord, but I cannot hear it directly. I can do something like arecord | aplay and it works, I can hear what I'm saying but, naturally, with a long delay. I have a TV tuner card and I redirect its audio output to the Line input of my soundcard and if I grab audio and video in software and then play it, it works synchronized, although some time behind reality. For most uses, it's not a big problem. But there've been cases in which i would have liked to have realtime feedback of input, such as when using a radio station here as a time synchronization source and one time when I connected a videogame console to the TV card, but the delay in audio made it unusable. With windows, I have feedback, but maybe the card itself is not capable of doing it and windows is emulating it with software, but I can not be sure. I've googled a lot for this, and I have updated the alsa modules but I have no idea about what can I do (if there's something I can do). I'll appreciate any help. Thanks! |
