[ΛΥΘΗΚΕ] Ο ήχος δεν παίζει με Karmic Koala και κάρτα ήχου M-Audio Audiophille 24/96

Για κάποιο λόγο, με το Karmic Koala ο ήχος μου πέρασε στις θρυλικές εποχές του Dapper Drake που τα προβλήματα ερχόντουσαν απανωτά και έτρωγα πολύ χρόνο για να βγάλω άκρη και να ακούσω όπως άρμοζε... Αφού όλα κάποια στιγμή φτιάξανε, ήρθε το pulseaudio και τα ξαναέκανε ρημαδιό :P Αφού πάλι κι αυτό "έστρωσε" στην πορεία, νά και οι καινούριες.. τζιριτζάντζουλες!

Ευτυχώς αυτή τη φορά δεν χρειάστηκε να παιδευτώ πολύ γιατί η (προσωρινή ελπίζω!) λύση βρέθηκε κάπου στα forums του ubuntu... Και την παραθέτω επίσης εδώ στα ελληνικά.

Λοιπόν, στο Ubuntu 9.10 Karmic Koala, είχα ένα πρόβλημα με την κάρτα ήχου μου M-audio Audiophille 24/96, το Karmic έβλεπε μόνο την digital έξοδο/είσοδο και δεν είχα ήχο. Τι πρέπει να κάνεις σε αυτή την περίπτωση; Αρχικά...

...προσθέτεις στο αρχείο /lib/udev/rules.d/90-pulseaudio.rules τα εξής: 

SUBSYSTEMS=="pci", ATTRS{vendor}=="0x1412", ATTRS{device}=="0x1712", ATTRS{subsystem_vendor}=="0x1412", ATTRS{subsystem_device}=="0xd634", ENV{PULSE_PROFILE_SET}="m_audio-audiophile-2496.conf"

... και μετά δημιουργείς ένα νέο αρχειο: /usr/share/pulseaudio/alsa-mixer/profile-sets/m_audio-audiophile-2496.conf με τα εξής περιεχόμενα:

; M-Audio Delta Audiophile 2496
;
; This card, based on the Via ICE1712 chipset, has two stereo audio channels
; (1 in and 1 out) and a separate S/PDIF digital stereo channel. Like with
; all ICE1712-based cards, this is exposed by ALSA as a single 10-channel
; device with some of the channels not connected.

; See default.conf for an explanation on the directives used here.

... και μετά από ένα restart είσαι κομπλέ! Δυστυχώς σε κάθε update του pulseaudio θα πρέπει να ξαναπροσθέτεις την μία αυτή γραμμή στο 90-pulseaudio.rules
