86faae8890 Removed the extra I2S input code. TDM and I2S port input code now shared. 2014-11-27 18:15:04 +00:00

673946b028 Standard I2S mode up and running again. Still needs more generalisation. 2014-11-27 17:58:07 +00:00

a6fdb9b22a Digital RX channels sent over in a separate loop in DoSampleTransfer(). Only I2S channels double buffered. 2014-11-27 17:57:28 +00:00

3ffbc99456 DoSampleTransfer now takes readBuffNo rather than actual buffer. Now two separate In buffers (was 2D array). Attempts to help compiler. 2014-11-27 12:44:39 +00:00

4d4c7b8f39 DSD ports now only enabled once - avoids issue with stop_clock and un-driven clock. ConfigAudioPortsWrapper() also simplified. 2014-07-14 14:51:13 +01:00

ccf7c66588 Sample shift up after volume macs no longer done in audio(). Now done in mixer(). This allows lower bits to be properly retained for 32bit (and DSD native) 2014-05-20 17:18:01 +01:00

671552767d Audio core now takes SET_STREAM_FORMAT_OUT command (rather than SET_DSD_MODE). It also accepts a sample resolution where appropriate. Deliver() also now has single return value. 2014-04-10 11:57:22 +01:00

8712acb539 deliver thread no longer waits for AUDIO_PLL_LOCK_DELAY - this was causing pop issues on rate change as DAC has mclk but no bclk/lrclk. This seems to cause issues. This delay now added to audio SF change in EP0 for safety. Related to BUG #14769 2014-01-20 18:13:54 +00:00
