Οκ. Πριν μπλέξουμε με τα αρχεία παραπάνω, ξανά άνοιξε το προηγούμενο:

Κώδικας: Επιλογή όλων

gksu gedit /etc/pulse/default.pa

Και άλλαξε την τελευταία γραμμή όπως πριν:

Μορφοποιημένος Κώδικας: Επιλογή όλων

set-default-source alsa_input.pci-0000_00_1b.0.analog-stereo

Αυτή τη φορά χωρίς το input που είχαμε βάλει πιο πριν. Αποθηκεύεις την αλλαγή και κλείνεις το αρχείο.
Μετά πάλι:

Κώδικας: Επιλογή όλων

pulseaudio -k && sudo alsa force-reload

Και βλέπεις αν διορθώθηκε. Αν όχι τότε ξανακάνε επανεκκίνηση και δες.

Όπως βλέπεις δεν έβγαλε σφάλμα.

Δείχνει να δουλεύει. ΟΜΩΣ εξαφανίστηκαν οι δύο πρώτες εγγραφές της C920 camera, η οποία έχει ενσωματωμένο μικρόφωνο. Γίνεται να υπάρχει και αυτό στις επιλογές?

Κάτσε να κάνω και ένα reboot.

[bobptz]

Βιάστηκα να μιλήσω. Μόλις έκανα reboot, το πρόβλημα επανήλθε. Όπως επανήλθαν και οι δύο εγγραφές για την κάμερα C920.

Τώρα?

Να θυμίσω ότι από τα τεστ που είχα κάνει, τις αλλαγές μάλλον τις αποθηκεύει. Αν κάνω αλλαγή, το μικρώφονο δουλεύει. Όταν όμως ξανανοίξω τα settings, χωρίς να κάνω απολύτως τίποτα το μικρώφονο παύει να δουλεύει και η επιλογή έχει αλλάξει. Κάτι λοιπόν συμβαίνει τη στιγμή που ανοίγω τα sound settings.
