Hi sunxi list! I recently asked about the status of ALSA audio for the BPi in mainline on the lemaker forums and I was pointed towards this patch:
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit?id=38e633f3f3756b5630c5eb66042e776d86764296 I've just tested 4.4.0 with that patch applied on my BPi. ALSA kinda works. I can play audio but its VERY quiet, even with the supposed volume control ('Power Amplifier'- there is no 'Main' or 'PCM' ALSA mixer controls) maxed out, which brings me onto the other issue. Not all of the ALSA mixer controls are present and the ones that are seem to be incorrectly labelled so it clearly needs some work yet: $ amixer scontrols Simple mixer control 'Left Mixer Left DAC',0 Simple mixer control 'Power Amplifier',0 Simple mixer control 'Power Amplifier DAC',0 Simple mixer control 'Power Amplifier Mixer',0 Simple mixer control 'Power Amplifier Mute',0 Simple mixer control 'Right Mixer Left DAC',0 Simple mixer control 'Right Mixer Right DAC',0 $ amixer controls numid=2,iface=MIXER,name='Left Mixer Left DAC Playback Switch' numid=5,iface=MIXER,name=' Power Amplifier DAC Playback Switch' numid=6,iface=MIXER,name='Power Amplifier Mixer Playback Switch' numid=7,iface=MIXER,name='Power Amplifier Mute Switch' numid=1,iface=MIXER,name='Power Amplifier Volume' numid=4,iface=MIXER,name='Right Mixer Left DAC Playback Switch' numid=3,iface=MIXER,name='Right Mixer Right DAC Playback Switch' Is anybody here working on the BPi ALSA driver? Is there a more complete patch I can test? You can see my thread with all the gory details here: http://forum.lemaker.org/forum.php?mod=viewthread&tid=22998&extra=page%3D1 Thanks! -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
