Alsa Problem under Ubuntu

[dafe123]

Hello,

I'm using Ubuntu and get the following Message, when I want to start Hairless:

ALSA lib conf.c:3357:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so
ALSA lib seq.c:935:(snd_seq_open_noupdate) Unknown SEQ default

RtMidiIn::initialize: error creating ALSA sequencer input client object.

terminate called after throwing an instance of 'RtError'
  what():  RtMidiIn::initialize: error creating ALSA sequencer input client object.
fish: “./hairless-midiserial” terminated by signal SIGABRT (Abort)

What can I do to run this program? Kind regards
