Generic PC x64 Build No HDMI Audio

#1

I want to use Lakka so bad, but haven’t been able to overcome the audio issue. I have followed the recommendations in this thread:

and the Lakka troubleshooting docs.

My current issue is there are no audio devices listed in the GUI and changing config files make no difference either.

The hardware is: ZOTAC mini-PC. Quad core AMD APU, 1.5ghz, 8gb DDR3, 1TB 2.5in hard drive

Here is a link to my SSH log output:

I appreciate any assistance, thanks!

update:

I can hear audio out of my TV over HDMI when performing this test.

Find some wav to play :

find /storage/roms -name *.wav or get one online

wget “http://samples.mplayerhq.hu/A-codecs/wavpcm/ahh.wav” -O sound.wav Then try to play some sound with hdmi devices : aplay -D plughw:card_id,device_id

aplay -D plughw:0,3 sound.wav aplay -D plughw:0,7 sound.wav aplay -D plughw:0,8 sound.wav

Can you try to make a test with nightly build ?

Thank you.

Kind regards,

@gouchi I installed Lakka-Generic.x86_64-2.2-devel-20181116001312-r28230-g20d25a6.img.gz and am experiencing the same issue. Thanks!

May you provide also the complete dmesg output, Lakka system log and audio log ?

Thank you.

#8

Can you try to edit configuration file and change to audio_device = "hdmi:CARD=HDMI,DEV=0" then provide Lakka system log ? If it is not reworking, redo the operation with audio_device = "hdmi:CARD=HDMI,DEV=1"

Thank you.

#9

@gouchi I have made the config changes and still no audio, here is the link to the two new syslogs. https://drive.google.com/drive/folders/1m4we3EzhKZVo2Rg2M90qj3nH6PUb_lgU?usp=sharing

Strange.

Can you add also the output of

grep audio_device /storage/.config/retroarch/retroarch.cfg

Thank you.

Lakka:~ # grep audio_device /storage/.config/retroarch/retroarch.cfg

audio_device = “”

Lakka:~ #

#12

How come you don’t have the audio_device configuration I asked you to test ?

#13

If you check the log files I uploaded after making the requested changes the config never reflects those changes. So strange, do you see anything I’m doing wrong?

#14

You need RA to be stopped before editing the configuration file otherwise it will be overwritten.

systemctl stop retroarch

then

nano /storage/.config/retroarch/retroarch.cfg

at last

retroarch -v

I was obviously not saving the config in the right location. I made the changes and copied it to text for you to look over, still no sound. I thank you for your assistance.

I got sound, I just loaded some roms back on and tested. No menu sounds, but game sounds…I’ll take it…Thanks!
