No audio on Raspberry Pi #4977

Closed padremayi closed 7 years ago

padremayi commented 7 years ago

Hi to all, I searched on the net in order to find something on this problem but I didn't find any response to this.

I compiled RetroArch from source code for Raspberry Pi in chroot environment on Ubuntu x64 machine.

All the cores are working fine except for the audio: I can't hear anything.

I launch the core with:

./retroarch -L core_name.so /path_to_rom

Any suggestion?

This is the log during launch:

hdmi_drive=2 is set but the problem is the failure on device initialization: RetroArch [ERROR] :: Failed to initialize audio driver. Will continue without audio

I tried with 1.5.0 and 1.3.6 code.

inactive123 commented 7 years ago

Which audio driver are you attempting to use?

padremayi commented 7 years ago

Hi, I tried all the available audio driver, ALSA, OSS, ALSATHREAD and PULSE but the audio doesn't work :-(

kivutar commented 7 years ago

Do you have dtparam=audio=on in your config.txt?

padremayi commented 7 years ago

Yes, I have that line in my config.txt but I just found the problem. In the retroarch.cfg I set

audio_driver = "ALSA" audio_device = "sysdefault:CARD=ALSA"

like the output of

aplay -L

and now it works ;-)

gouchi commented 7 years ago

You can switch audio device from the gui.
