Hi everyone,
the developer of the RAVENNA Driver supported me and suggested not to
use the Ravenna card directly but to use it via ALSA plugin.
So I created this configuration file in /etc/asound.conf
Code:
--------------------
pcm.source_1 {
type dmix
ipc_key 0x11111
slave {
pcm "hw:CARD=RAVENNA"
buffer_size 4096
channels 4
rate 48000
format S24_3LE
}
bindings { 0 0 1 1 }
}
--------------------
I tested first with "speakertest" and "aplay":
Code:
--------------------
sudo speaker-test -D plug:source_1 -r 48000 -c 2 -t sine
sudo aplay --dump-hw-params -D plug:source_1 -r 48000 -c 2 -f S24_3LE
test48.wav
--------------------
Both worked without any issues.
Than I started squeezelite:
Code:
--------------------
a@audioserver:~/programs$ sudo ./squeezelite -n AES -d all=debug -o
plug:source_1
--------------------
Now the AES Receiver (Audio-DSP) connected without any issues (Had
missing packets before) and I could play a track in LMS.
However the sound was broken. Too soft, choppy. In the log file I saw
lots of strange outputs. I guess there is just a minor config issue.
Would appreciate if someone could support here. Thanks a lot.
Code:
