No audio on Pi3 after upgrade from 3.8.1 to 4.1

JPL

I recently powered on my Pi3 running RetroPie 3.8.1 for the first time in a few months, and noticed there were a couple major version upgrades waiting so I did them via the usual wiki-recommended method. Everything seemed fine until I noticed I wasn't getting audio in any emulators (or in Emulation Station itself).

I searched through a few existing troubleshooting threads for this and nothing has worked. I've added these lines to my /boot/config.txt:

hdmi_drive=2
hdmi_force_hotplug=1
hdmi_force_edid_audio=1

but that doesn't seem to change anything.

When I try to play a test sound from the command line with sudo aplay /usr/share/sounds/alsa/Front_Center.wav, I get this:

ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4259:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

Make sure you have

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

in /boot/config.txt

Hi @JPL

If you go into the Audio Mixer in the RetroPie menu (it may be Audio Settings, I can't remember right now), does the volume control appear and which device does it say at the top of the screen?

That worked, thanks a billion!

Hi to everyone! Got the same problem on pi zero. I have a dual boot system (retropie and osmc). Audio works fine via HDMI in osmc, but not in retropie. I have all 4 lines in my config.txt:
#hdmi_drive=2
#hdmi_force_hotplug=1
#hdmi_force_edid_audio=1
#dtparam=audio=on
but still no luck. Can anyone help me, please?

@yari i think you have to uncomment thoise lines, remove the # symbol and save changes, then test.

I've the same problem, no audio, but just when trying my video capture device, an Avermedia LGP, and I have in my boot/config.txt file these options enabled

hdmi_force_edid_audio=1
dtparam=audio=on
hdmi_drive=2.

any clues?

@mahcneto i could be wrong but i think you need to hashtag out the hdmi drive line for the force edid audio to work

yari

@mahcneto thank you, it worked! the problem was in symbol "#", I didnt know that

mahcneto

I'm glad it worked! I tried to write that symbol but i got the word hashtag instead on the forum, go figure :p

@mahcneto you should put configs in code blocks or else the forum will think it's styling. See the link in my signature or the compose? link when making a reply
