Hello everyone I will soon acquire Mini2440 board and I'm currently gathering resources and preparing toolchain. I'm mostly interested in sound processing, I would like to build custom DSP effects with some supporting GUI made in Qt. I noticed that the board has two audio inputs - one is connected to onboard mic, and other is on connector CON10. I would like to connect line-in signal to this input. Audio codec UDA1341 supports different levels of input signals by changing PGA settings over I2S. How is this supported from Linux? At which stage during power-on is UDA1341 configured? Has anybody here worked with audio input? Is there a project available? Thanks Josip
Audio input
Hi, Did you go forward with your project ? If yes, can you open the audio device (UDA1341) in Read/Write mode ... Regards
You can change parmters via IOCT. I have port fmpeg and also written an applicaiton for auido capture but the board audi cannot be played in the PC. The sound is so low that nobody can listen to it. I wonder if the problem is in 16 bit PCM capture, little endian x big endian. I´m trying to fix it but had no success.
