Hi everyone,
This patch set adds the support for what Allwinner calls the codec on their SoCs.
This codec is actually a combination of a codec and DAI, tied together in a single memory-mapped IP. It is completely standalone, and outputs directly the analog signal.
While it supports both playback and capture, the capture is not implemented in this patch, and will be posted eventually as a separate one.
This set, in order to be functional, has a dependency on the audio clocks patch set posted separately. However, it doesn't needs this to compile properly, so I guess it can be merged without really caring for the merging status of the clock patches.
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:
- All switches on
- Mute pre-amplifier
- Mute RMR
- Pre-Amilifier Mute Off
.. Music stays off 5. Toggle Pre-Amplifier twice - output turns on
Unfortunately, I don't have access to that SoC or that setup.
Do you have another A10 board with a simpler audio setup, like a cubieboard?
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
That one is weird, I'll look into this.
This also appears on my Cubietruck, when using the dts patch from Hans' sunxi-wip branch, which is the same patch, albeit for a different dts file, as Priit.
The immediate culprit seems to be the routing property, though I'm not sure what it should be set to, or what extra drivers might be needed.
