rocker: Disable mute-on-pause, due to a platform kernel bug. In short, the display fading back in after a pause resuming interferes with the audio codec, causing BadThings(tm) that cannot be recovered from This really is just avoiding a known trigger; there's no guarantee this condition won't occur under random circumstances during normal use, and there's no good way to work around this from within rockbox. I suspect the underlying problem is that both the display control and codec control share an i2c bus, but the kernel drivers implementing them isn't using proper linux bus access/locking.

hosted pcm-alsa improvements * xduoo x3ii/x20: Better line out support * less granular volume settings (too many steps before) * Better handling of swiching sample rates * Log actual sample rate in debug menu Most credit goes to Roman Stolyarov Additional integration [re]work by myself Change-Id: I63af3740678cf2ed3170f61534e1029c81826bb6 2020-10-01 02:12:35 +00:00
pcm: Get rid of pcm_play_pause() and associated APIs Nothing in the core has used it for some time. It's exported to the plugin API but the last plugins to use it were switched to the mixer API back in 2011. This allows us to get rid of pcm_play_dma_pause() from all audio drivers Change-Id: Ic3fa02592316f84963e41d792d1cabb436d1ff6b 2020-10-31 00:30:27 +00:00			`//#define AUDIOHW_MUTE_ON_STOP`
