Im trying to play a video. Im getting the following error:
E/gralloc_ranchu( 2305): updateHostColorBuffer: Unexpected DMA
E/ ( 2305): lockAndWriteDma: ERROR: No DMA context bound!
Im just using the sample code from https://pub.dev/packages/chewie and the video player just shows a green screen and doesnt do anything. Any ideas?
EDIT: Some more comments that may help?

This is an open issue with no known workarounds at present. It might be helpful if you could also provide the video that you're trying to load for easier replication of the issue.

It worked just fine on my previous interaction with the camera.

Has anyone had a similar problem?
This link says it means there is something wrong with the esp file system rendering it "broken"... Not sure if there is a way to fix the issue though.
EDIT:
I found that if I disconnected some of my peripherals from esp32, the error went away. Perhaps too much power was being drawn.
I'm learning how to use the Metal API. I've been following this tutorial: Audio Visualization in Swift using Metal and Acceleration
Building the project in Xcode succeeds but the program does not function and I get these errors in Xcode console:

I'm using a MacBook Pro with an integrated GPU. Intel and AMD Radeon with automatic graphic switching. If anyone has any advice to fix or a work around, that'd be great.
I am trying to record audio with the PS Eye on a raspberry pi model b plus (I have tried with older b models and the same issue occurs as below).
I am able to record, and playback the recording with arecord/aplay so the mic is working. However, I want to increase the mic volume as the recording is very low.
When I attempt this in alsamixer, it exits with the following error when I use F6 to change to the PS Eye soundcard:
cannot load mixer controls: Invalid argument
I also notice that the alsa-utils service will fail when the PS Eye is plugged in (fine otherwise):
sudo service alsa-utils restart
[FAIL] Shutting down ALSA...warning: 'alsactl store' failed with error message 'alsactl: get_control:259: Cannot read control '2,0,0,Mic Capture Volume,0': Invalid argument'...failed.

done.
The problem seems to be the controls definition of the PS Eye. I would like to know the following:
Where does alsamixer load the controls for a particular device from? Are they in the driver?
Is there a way to increase the mic volume another way?
I am not using Pulseaudio yet but will try it if I can't fix this in alsa.
thanks
Sytem logs:
Without pulseaudio installed, neither restarting alsa or trying to open the controls in alsamixer produce anything in the system log. If pulse audio is installed however, trying to open the controls in alsamixer gives:
