On most recent firmware (archlinux-arm)
using audio_pwm_mode=2
makes MPD music sound slower, like some frequency rate error.
audio_pwm_mode=1, sound good.

Is it ok to offer my services here?
I can code this for you, email me at [email protected]

Sorry to revive this old thread.
Is it possible to update libvgfont to accept unicode characters?

fredfs

I am looking for something like this. Do you mind sharing the code? Hi folks, Thanks for the advice. In the end for various reasons I decided to write my own thing from scratch using libx11. Seems to be doing what I need which is basically checking for a message left in a file in /tmp every few seco...

I see that the stock /etc/network/interfaces has no entry like:
allow-hotplug eth0
ou
auto eth0

Why ?
What is the default behavior when no option like these is set?

Is there any problem adding allow-hotplug eth0? I still want dhcpcd to handle dynamic or static ip settings.

fredfs

Is it possible to tweak it a bit more to accept layer number as argument on the command line?

I have been testing youtube-dl inside the pi, most of the time it downloads and gerenates a playable movie but sometimes the file youtube-dl creates is not playable by omxplayer. " Vcodec id unknown: a8" I dont know what are the omxplayer limitations in terms of codecs. Any recipe to youtube-dl alwa...

Try yourself to open a music wav file, downsample it to 6 bits, and listen to the crap result. This is not what you hear in raspberry analog out. It is not audiophile 7th wonder, but you cannot say it is 6 bit, it IS 16 bit, with quality compared to most mobile phones audio output. The 'only' way to...

Do I need to remove npt, ntpd and disable theier services from systemd? If you can't get ntpd to run take a look at htpdate. http://www.vervest.org/htp/ which doesn't use any special ports, it gets the time over regular http (port 80). That's available to install using sudo apt-get update; sudo apt-...

Using command line omxplayer with 720p-1080p/25fps (~4minutes) mp4 videos, I have been suffering with frequent audio grasps/shuttering every ~3minutes. Is there any omxplayer option flag , or /boot/config.txt line I could try fix it? As of now I am using stock foundation's raspbian lite (no desktop)...

fredfs

Omxplayer has a strage behavior when on negative layer (example -10), if there is a tranaprant png layer over it, you dont see omxplayer layer. If omxplayer is on layer zero or above, you can render transparent png over it without problems.
Why?

How can I kill the tty1 framebuffer or prevent it from starting at all?

fredfs

Hello, I would like to play images and videos, and use negative frambeffer numbers (example, omxplayer --layer '-10')
But the command prompt at frambuffer 0 stays on top of negative buffer.
I dont use the command prompt, how can I kill it, or prevent it from starting at all?

fredfs

I need to solder the power cable to the PI but still PASS trought the fuse.
Is it possible?

I dont want to bypass the fuse (like the GPIO instructions I have found).

Thank you!

fredfs

I need to add a binary file (gpu related code) inside the /boot partition, and execute it at boot, when the GPU is avaliable.
How is this possible?

fredfs

can we make this ncurses?

fredfs

Is there a source code on github?

fredfs

Hello, I am using omxplayer on a command line only raspbian setup to play a folder of mp4 movies with sound. My bash script loads a playlist.txt file and start looping over the listed files. It works but there is a notorious gap between files. Is there any way to avoid this gap, or in some way pre-b...

fredfs

Are there more hello_audio examples? I want to use it to create some interface sounds, can anybody help me make it play a simple "click" sound instead of the looping siren?

fredfs

Thats is too late, I was looking for something as soon as the initial boot stage. Maybe using hello_audio code? When testing some setups, I use a similar idea, although often a video (no sound) but audio works fine too. Using omxplayer is a good idea, as it doesn't depend on the state of alsa. Alsa ...

Desktop speakers...

Does it really matter?

fredfs

Maybe your only help would be using a DAC, like Hifyberry, that does not suffer electric interference?

fredfs

I am trying to have a boot sound on my pi robot. So when the power in on, something comes out from speakers connected to the analog audio output. So far I have all these lines on the very first rc boot script (rcS) /usr/bin/omxplayer -o local /home/bootsound.wav and /usr/bin/aplay /home/bootsound.wa...

Courious about what are the differences between HifiBerry, PIFI and IQaudIO dac, if any

fredfs

Hello. I am looking for some advice on what is a good DAC for the Raspberry Pi. The cheapest I can find, is the chinese " Pifi DAC" wich is supossed to work with the same drivers the Hifiberry works. Any one had the oportunity to test it? Are they worth? Second there are the Hifiberry, wich seems to...
