According to the datasheet from Digikey, the part numbers mean this:
KT11 - this line of switches
P2 - hard actuator, 2.36 mm travel
SA3M - Right angle with pick & place tab
3 - 3 (?)
5 - gold plated
LFG - RoHS compliant and compatible. Gold plated
So it looks like it is compatible
Looks like that Linux-3.15 repo is simply missing the two commits that adds omap-abe-mmap.c: https://github.com/Risca/linux/commits/omap5_uevm-3.8/sound/soc/omap/omap-abe-mmap.c
Notably, the second commit is some kind of big bang "Just fix it" commit before release (my interpretation).
However...
I finally got some time to work on this and I got some news!
Before you get too excited: no, I haven't been able to play sound yet :( but I've made some realizations.
The old Linux-3.8 driver actually have 2 audio "platform drivers":
omap-pcm.c - introduced in 2008 with support for Nokia...
Those look like files used by Letux-OS related to packaging the kernel and userspace configurations. It may be relevant for the Pyra, but has no place among the kernel code (IMO)
I've sent a patch to the Letux mailing list and notified @hns about the findings. He sounded very excited in his reply :D He was gonna do some testing on his PandaES asap. The PandaES is a similar architecture to the Pyra.
I've also pushed the code I used for debugging this issue...
Finally got some work done on this today, and I might have found the reason the AESS firmware is not running as it should!
You see, early during firmware loading we do this:
static int aess_load_fw(struct snd_soc_component *component,
struct snd_soc_tplg_hdr *hdr)
{...
Now I understand, thank you.
I realize I'm not really the target audience for the client. I install maybe 2-3 games/year and it's mostly story driven single player games you can complete. Don't care much for competition or achievements. I only have a GoG account (shut down my steam account a...
I just finished Disco Elysium: Final Cut. Apart from some very minor interface bugs, I wholeheartedly loved it. From the outstanding voice acting (just the narrator had over 350 000 words) to the absolutely fantastic dialog and story :) The mood and setting is thoroughly well described and I...
Unfortunately, I wasn't able to fix the sound issues, then I ran out of free time. Working on the sound driver has a startup cost that is usually longer than what I have time for on any given day :(
I always had issues with buzzing and noise on the pi's builtin audio port. The HiFi hats available for the pi have been very affordable and great when I've used them,
