U sustini sta god ukucam na "adevice=XXXX" dobijam isti izlaz samo sa redom "ALSA lib pcm.c:2099:(snd_pcm_open_noupdate) Unknown PCM XXXX"
Prosli put sam zaboravio da kazem da ako one crvene tackice nisu na "line" vec na "CD" tada mplayer ne snima zvuk, ali zvuk ode na zvucnike i kad se prekine snimanje zvuk se ne iskljucuje, nego pocinje da susti.
Probao sam da snimam sa "cinerelom". I kod nje kad krene snimanje zvuk ode na zvucnike a nikakav zvuk ne snimi. Takodje kad se prekine snimanje ostane sustanje na zvucnicima. (cinerela mi nikako ne snima zvuk bez obzira gde su one crvene tackice).
Imam neki utisak da se desava sledece:
programi za snimanje aktiviraju TV kartu i ona krene da salje zvuk na zvucnu. Alsa preuzme to sto ima na ulazu i pusti na zvucnike, i tu se otprilike zavrsi sva prica. Kao da programi za snimanje bas najbolje ne komuniciraju sa Alsom.
