The first version of Quirky Alpha I had no problems with the sound.Perhaps you have installed something that has messed things up.
I have just booted up my 8.0.19 build on the Pi2, which is the same as 8.0.18 as far as sound is concerned, I think.
The subsequent versions I have had the same problem of alsamixer and
amixer not working (and retrovol giving me a blank window)
Here's an example...
Code: Select all
# alsamixer
cannot open mixer: No such file or directory
To stop stuttering of audio playback I must put in the following in my
config.txt
Code: Select all
hdmi_ignore_edid_audio=1
which I assume uses alsa. alsamixer works in fatdogarm
This is a trick I learned in fatdogarm.
The odd thing is that when I install omxplayer v7 3.7
the sound is perfect on my TV set and also over the analog jack.,
but just that app. It uses totally different media libraries.
I'll try the following tonight.
1) Boot up with default config.txt , set up my sound
(which will be difficult because of distorted TV screen ), then power off
2) Reboot again to see if sound settings are persistent and check for stuttering problem
3) Change my config.txt file to
Code: Select all
disable_overscan=0
start_x=1
gpu_mem=128
hdmi_group=1
hdmi_mode=4
# Safest video mode
#hdmi_safe=1
# If audio stutters uncomment the next line to output sound to stereo jack...
hdmi_ignore_edid_audio=1
# Berryboot settings, do not change
#initramfs berryboot.img
#[pi2]
#kernel=kernel_rpi2_aufs.img
initramfs initrd.rpi2
[pi2]
kernel=vmlinuz.rpi2
