RPI0 and RPI0W are expected to work (without WiFi, and one needs fdt files \todo where from?).RPI1, RPI2, RPI2-1.2, RPI3, RPI3 (except RPI3 builtin WiFi and bluetooth).( Raspberry Pi image by Christopher Lee used under CC-By-2.0 license) What works NetBSD 8 Xenon death flash (Raspberry Pi 2 is camera-shy).Power supply needed (or: why there is a little rainbow square in the top-right corner?).Updating the firmware version in the NetBSD sources. I have 20 years of linux experience but this is my first try with a raspi device. I did also try a 4-pole 3.5mm A/V cable from an old camcorder, and I do get sound, but as implied by the figure of the original article, this camcorder type cable will have audio/right-channel on the yellow (nominally video) plug. So the problem with “no audio on 3.5mm” is not a function of the cable, it is about getting the output enabled. Can possibly fix this by forcing some X11 settings, have not tried yet.įinally, about the 3.5mm A/V jack and cable requirements: I can report that I can get audio through a 3-pole audio cable, no 4-pole cable needed. Summary: There exists a workaround, but video resolution will then be wrong. This also makes no difference, even after a reboot (with HDMI connected during this reboot, since that is the case one would want to test). Further, I have tried the command “sudo raspi-config” and choosing successive menus “8=advanced-options” then “A9=audio” and chosen the 3.5mm as output. I have tried the command “amixer cset numid=3 1”. Now, if booted with HDMI plugged-in, I have found no no way to get the sound switched over to the 3.5mm jack. That is an ~ok workaround, but when you plug in HDMI after boot it will come up with low resolution video (640×480, VGA). The following is observed with OS raspbian wheezy 7.įirst, I can report that analog 3.5mm audio out on a raspi2 works as long as the raspi2 is booted with the HDMI unplugged. I recently acquired a Rapsberry Pi 2 (raspi2 for short) and thought it might be helpful to report my observation about the 3.5mm jack with respect to audio.
