It works on Gemei G9 tablet which has also extra chip that automatically switches output over from internal speakers to headphones when connector is inserted. Now I noticed some weird things: When I have all the switches as ON in alsamixer, and I start disabling them, I get following weird results. Left Mixer Left - LML Right Mixer Left - LMR Right Mixer Right - RMR Very faint output: LML - ON RML - Mute RMR - ON Output works fully: LML - Mute RML - Mute RMR - Mute When I Mute Pre-Amplifier and fiddle any of LML, RML or RMR, the output stays mute even after setting Pre-Amplifier Mute back on: 1. All switches on 2. Mute pre-amplifier 3. Mute RMR 4. Pre-Amilifier Mute Off .. Music stays off 5. Toggle Pre-Amplifier twice - output turns on And also following in dmesg: sun4i-codec 1c22c00.codec: Codec <-> 1c22c00.codec mapping ok sun4i-codec 1c22c00.codec: ASoC: no sink widget found for Headphone Jack sun4i-codec 1c22c00.codec: ASoC: Failed to add route HP Left -> direct -> Headphone Jack sun4i-codec 1c22c00.codec: ASoC: no sink widget found for Headphone Jack sun4i-codec 1c22c00.codec: ASoC: Failed to add route HP Right -> direct -> Headphone Jack With following patch to DTS: +&codec { + routing = "Headphone Jack", "HP Left", + "Headphone Jack", "HP Right"; + status = "okay"; +}; > > Let me know what you think, > Maxime > > Emilio López (1): > ASoC: sunxi: add support for the on-chip codec on early Allwinner > SoCs > > Maxime Ripard (1): > Documentation: bindings: Add the Allwinner A10 codec bindings > > .../devicetree/bindings/sound/sun4i-codec.txt | 33 + > sound/soc/Kconfig | 1 + > sound/soc/Makefile | 1 + > sound/soc/sunxi/Kconfig | 11 + > sound/soc/sunxi/Makefile | 2 + > sound/soc/sunxi/sun4i-codec.c | 720 > +++++++++++++++++++++ > 6 files changed, 767 insertions(+) > create mode 100644 Documentation/devicetree/bindings/sound/sun4i- > codec.txt > create mode 100644 sound/soc/sunxi/Kconfig > create mode 100644 sound/soc/sunxi/Makefile > create mode 100644 sound/soc/sunxi/sun4i-codec.c > > -- > 2.5.1 > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
