Hello all.
Just another threat with audio input/output problems.
I use Peppermint 5.

Starting baudline I get the /dev/audio No such file or directory. Following a threat and making a symlink:

sudo ln -s /dev/dsp /dev/audio
./baudline -record // start prg.
error message:
/dev/audio Input/output error

I spent one day to try several threats I found on Google without succsess

Hi,

Baudline by default uses the old OSS linux sound drivers. There are not provided anymore.

I don’t know Peppermint Linux but if it uses the pulseaudio server, you can send the flow through standard input & output:

parec --channels=1 --latency-msec=2 | ./baudline -stdin -stdout | pacat

If your disto supports ALSA, you may try the alsa-oss that provides an OSS compatibility layer:

aoss ./baudline

cheers
