* Radio and radio recording for Samsung YH-920.Szymon Dziok2014-06-18
| | | | | | | There is no simple method to detect radio through the 3-wire interface, so it's not implemented for the YH-925 for now. YH-920 always has a radio. Change-Id: Iea484d752915fcd40dbbbd7dbbf13e81aaf548db
* Samsung YH820/YH92X: Improve recording.Szymon Dziok2014-06-18
| | | | | | | | Because of architecture of the codec it's always necessary to route the input signal from ADC to DAC, in order to have a control over the monitoring volume and in order to hear anything while recording. Change-Id: I1089894c949ab7371857d74aedb6bdf5a7d39c41

* Do some cleanup, adjustment and a couple fixes to recent sound changes.Michael Sevakis2013-04-22
| | | | | | | | | | | | | | | | | | | | | * SOUND_x enum can be generated by audiohw_settings.h along with settings entries and sound_val2phys. * VOLUME_MIN and VOLUME_MAX are no longer necessary within sound.c. If you need them, they are for target-defined purposes. * Fix up SDL volume implementation in sdl.c. Move sim volume calculation code to pcm-sdl.c. * Min trigger tresholds were based upon VOLUME_MIN for some reason. These setting have nothing to do with playback volume. Since it is no longer present, set these at -89dB which is the minimum peak meter sensitivity setting. * Fix an oversight in wm8758.c. I forgot to add the dB->register conversion to audiohw_set_volume. Change-Id: Ie1df33f1793eee75e6793f16bc7bddd16edb7f75

* Straighten out the mad twisted state of sound.c and related areas.Michael Sevakis2013-04-15
| | | | | | | | | | | | | | | | | | This is going right in since it's long overdue. If anything is goofed, drop me a line or just tweak it yourself if you know what's wrong. :-) Make HW/SW codec interface more uniform when emulating HW functionality on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to- DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX" APIs are all in sound.c with none in DSP code any longer. Reduce number of settings definitions needed by each codec by providing defaults for common ones like balance, channels and SW tone controls. Remove need for separate SIM code and tables and add virtual codec header for hosted targets. Change-Id: I3f23702bca054fc9bda40f49824ce681bb7f777b
* Remove pcm_mute() which has been unused since r19308Rafaël Carré2010-04-27

working on 820 & 925 (untested on the 920). No battery readings. No recording. No plugins. Keymap needs work. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21083 a1c6a512-1295-4272-9138-f99709370657
