Musiland I2S

One of the reasons I had to measure the I2S frequency was because I connected the MUSILAND 01-MINI to the WM8741 DAC by tapping the I2S lines. Here you can see the MUSILAND device (which implements asynchronous USB transfer and supports up to 192 KHz sample rate content -and good reviews in the audio forums). I took it out of its metal casing, attached it to a plastic board and tapped the I2S lines that connects the fpga to the internal DAC
