Hi,
AESS / Audio is one of the biggest remaining issues we have on the Pyra. Everything else seems to work good enough for a start now, but missing audio on a gaming handheld is a bit annoying :)
With some kernel version, speaker output stopped completely, but Nikolaus is currently looking into what changed with each kernel version and when exactly it stopped working to get this to work again, at least.
This would make audio work again, but it would still have the following issues:
- Weird setup of sound devices: You would expect that the system would provide
different audio outputs (speakers, headset) to the Linux system, but AFAIK, for some weird reason, there's a 4-channel device where the headset is channel 1 and 2 and the speakers are channel 3 and 4. This should be fixed, so that Pulseaudio shows different outputs (like on normal Linux systems) so you can move around your streams where you want them to have.
- AESS... well, not mandatory for a first release, but in the future, it should
work, as software mixing just unnecessarily needs CPU power.
@Marek: I know you've been working on this, question is: Are you still doing something here? Or have you given up for now?
I've given up because changes would need a lot of time as sound firmware loading was changed rapidly.
@All: If no one wants to work on that (or CAN work on that), I'm thinking of hiring a team that could do this in fulltime. Nikolaus pointed me to these guys: https://bootlin.com/engineering/technical-support-and-consulting/
They are very good but I expect they will not be cheap :)
Does anyone have experience with them or have any other reliable freelancers by hand which I could hire for that.
Geez, I didn't think the TWL6040 would be SO hard to get to work properly...
Thanks in advance :)
