ALSA and pygame.midi.init() function problem on Debian

Question

I can't call the pygame.midi.init() function on my Debian machine. Running the following code:

import pygame, pygame.midi
pygame.midi.init()

will result in the following errors:

ALSA lib conf.c:3009:(snd_config_update_r) Cannot access file /etc/alsa/alsa.conf

ALSA lib seq.c:935:(snd_seq_open_noupdate) Unknown SEQ default

Can any one help?
