[Sound Blaster Audigy 2 ZS] Audio doesnt work - snd_pcm_open

I am trying to play audio files :

playaudio file.mp3

but I have this error :

snd_pcm_open failed: No such file or directory
Couldn’t play ‘file.mp3’

My sound card is a sound blaster so I follow the doc and do that :

io-audio -dsb &

but I still have the same error, and I have no files in /dev/snd…

Which soundblaster? Support for most Creative PCI model has been dropped.

My sound card is a Sound Blaster Audigy 2 ZS…

but io-audio is not launched at the startup, is it normal ?

This card is not supported. Don’t know about io-audio but I would assume that since no supported sound card is detected there is no need for io-audio.
