sc_usb_audio Change Log sc_usb_audio Change Log
======================= =======================
6.12.7 6.13.0
------ ------
- ADDED: Device now uses implicit feedback when input stream is available (previously explicit - ADDED: Device now uses implicit feedback when input stream is available (previously explicit
feedback pipe always used). This saves chanend/EP resources and means less processing feedback pipe always used). This saves chanend/EP resources and means less processing
burden for the host. Previous behaviour available by enabling UAC_FORCE_FEEDBACK_EP burden for the host. Previous behaviour available by enabling UAC_FORCE_FEEDBACK_EP
- CHANGE: Mixer and non-mixer channel comms scheme (decouple <-> audio path) now the identical - RESOLVED: Exception when SPDIF_TX and ADAT_TX both enabled due to clock-block being configured
after already started. Caused by SPDIF_TX define check typo
- RESOLVED: DFU flag address changed to properly conform to memory address range allocated to
apps by tools
- RESOLVED: Build failure when DFU disabled
- RESOLVED: Build issue when I2S_CHANS_ADC/DAC set to 0 and CODEC_MASTER enabled
- RESOLVED: Typo in MCLK_441 checking for MIN_FREQ define
- CHANGE: Mixer and non-mixer channel comms scheme (decouple <-> audio path) now identical
- CHANGE: Input stream buffering modified such that during overflow older samples are removed
rather than ignoring most recent samples. Removes any chance of stale input packets
being sent to host.
