No sound using Lubuntu

RetroArch Linux devices
#1

Hi all, I’m having a heck of a time getting sound output using retroarch. I can’t get any sound at all. Ideally, I’d like it over HDMI but I can’t even get analog. All my other applications work well using ALSA. I tried specifying audio driver to alsa and the following options here: https://pirraste.wordpress.com/2014/02/28/retroarch-alsa-audio-over-hdmi-working/

I tried setting the audio out rate to 44100 and 48000. I tried reading my aplay -l and specifying hw:0,3 as my audio device. I tried aplay -L and specifying hw:CARD=PCH,DEV=3 in my audio device

I then tried to install pulseaudio and change the audio driver back to pulse. Then I left the audio_device blank and still no sound. I entered into audio_device: pulse, default, analog-stereo, the hardware IDs mentioned above. I checked that pulseaudio is running with pgrep -l pulseaudio. It’s also listed as an output with aplay -L.

I am completely stumped here. Any ideas? Or can anyone point to documentation that can help me?

thanks, I’d love to try to use retroarch on my htpc.

Head over to the Lakka subforum. There are a few threads about HDMI audio that should be helpful.

Is it possible to get a log ?

retroarch --menu --verbose >> log.txt 2>&1

Yes. There is no sound via analog or HDMI audio.

Here is a log using the pulse driver and audio_device = “”

I don’t know how to test if pulse is working because nothing else I know uses it. I was able to issue the aplay -D command to play a test file on my default analog output device which works.

Here is a log using pulse driver and specifying audio_device = “hw:0,0” It reports Failed to start audio driver. Will continue without audio. Is that due to my syntax of specifying the audio device?

How do I specify an audio device using pulse?

#5

Can you try to start RetroArch with “fresh” configuration file ?

mv ~/.config/retroarch/retroarch.cfg ~/.config/retroarch/retroarch.cfg.bak

Then launch retroarch, you should be able to switch audio device directly from the Audio Settings by pressing left or right key.

If you can’t, you can try to add manually audio_device in the configuration file with aplay -L.

mv ~/.config/retroarch/retroarch.cfg ~/.config/retroarch/retroarch.cfg.bak

Then launch retroarch, you should be able to switch audio device directly from the Audio Settings by pressing left or right key.

If you can’t, you can try to add manually audio_device in the configuration file with aplay -L.[/QUOTE]

OK, that worked! I am still unable to specify the audio device using the retorarch GUI, but I will try to manually specify it and report back.

Thank you very much!
