Hello,
I'm using Arch Linux (AArch64) for the first time on a Raspberry Pi 4. I
need to use HDMI sound and the first HDMI port on the pi is card 0. If I
try to use aplay to play a sound file it prints:
aplay: set_params:1343: Sample format non available
Available formats:
- IEC958_SUBFRAME_LE
I find that I can play audio through HDMI by specifying the sample
format. eg.
aplay -D iec958 mysound.wav
What I'm stuck with is trying to configure ALSA to make this
specification. I've tried the following in my ~/.asoundrc
pcm.!default {
type plug
slave {
pcm "hw:0,0"
format IEC958_SUBFRAME_LE
}
}
While this produces no Alsa syntax errors when I use aplay, it still
won't play the audio and prints:
Playing WAVE 'wav48k.wav' : Signed 16 bit Little Endian, Rate 48000 Hz,
Stereo
aplay: set_params:1343: Sample format non available
Available formats:
- IEC958_SUBFRAME_LE
Can anyone please help?
Thanks,
Iain
