Scusami tanto se ieri non ti ho potuto rispondere.
Ho provato anche questo tentativo ma niente…i dispositivi elencati sono gli stessi…cosa intenti per:
“l’output audio di che tipo è: stereo, 4 canali, 5 canali, 6 canali, 8 canali?”
[/quote]
ok. terzo tentativo fallito. domanda:
I volumi al riavvio erano a zero?

La macchina della quale mi hai segnalato il link ha come processore:

Dove c’è scritto che ha un athlon tk-55? link:

ho letto varie guide e suggerimenti della comunità in merito al problema che ci assilla.
la guida da te segnalata l’ho gia letta, come ne ho lette molte altre.
Un problema in linux si risolve solo se ci si documenta.
Riepiloghiamo le notizie che ho raccolto, così ti chiarisco qual è il problema:
- abbiamo un portatile asus che ha un problema sul riconoscimento dell’hardware audio.
Il modello è , per il momento, sconosciuto. ( io suppongo che si tratta di un F5N, sei tu che dovresti confermare o smentire questa supposizione)
La scheda audio è segnalata da lspci come una MCP67 nVidia.
La MCP67 nvidia non esiste come scheda audio.
Esiste invece una scheda nvidia che monta un chip audio Realtek “annegato” al suo interno.
Il sito ALSA-project ovvero il progetto di architettura sonora in Linux dichiara che questo tipo di chip viene gestito correttamente dal modulo hda_intel ( e se lo dicono loro, io ci credo), ma attenzione ci sono i seguenti settaggi da eseguire in sede di caricamento del modulo a seconda del chip:
Module snd-hda-intel
Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8),
ATI SB450, SB600, RS600,
VIA VT8251/VT8237A,
SIS966, ULI M5461
model - force the model name
position_fix - Fix DMA pointer (0 = auto, 1 = none, 2 = POSBUF, 3 = FIFO size)
probe_mask - Bitmask to probe codecs (default = -1, meaning all slots)
single_cmd - Use single immediate commands to communicate with
codecs (for debugging only)
enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
power_save - Automatic power-saving timtout (in second, 0 =
disable)
power_save_controller - Reset HD-audio controller in power-saving mode
(default = on)
This module supports one card and autoprobe.
Each codec may have a model table for different configurations.
If your machine isn't listed there, the default (usually minimal)
configuration is set up. You can pass "model=<name>" option to
specify a certain model in such a case. There are different
models depending on the codec chip.

The model name "genric" is treated as a special case. When this
model is given, the driver uses the generic codec parser without
"codec-patch". It's sometimes good for testing and debugging.
If the default configuration doesn't work and one of the above
matches with your device, report it together with the PCI
subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
ML (see the section "Links and Addresses").
power_save and power_save_controller options are for power-saving
mode. See powersave.txt for details.
Note 2: If you get click noises on output, try the module option
position_fix=1 or 2. position_fix=1 will use the SD_LPIB
register value without FIFO size correction as the current
DMA pointer. position_fix=2 will make the driver to use
the position buffer instead of reading SD_LPIB register.
(Usually SD_LPLIB register is more accurate than the
position buffer.)
NB: If you get many "azx_get_response timeout" messages at
loading, it's likely a problem of interrupts (e.g. ACPI irq
routing). Try to boot with options like "pci=noacpi". Also, you
can try "single_cmd=1" module option. This will switch the
communication method between HDA controller and codecs to the
single immediate commands instead of CORB/RIRB. Basically, the
single command mode is provided only for BIOS, and you won't get
unsolicited events, too. But, at least, this works independently
from the irq. Remember this is a last resort, and should be
avoided as much as possible...
MORE NOTES ON "azx_get_response timeout" PROBLEMS:
On some hardwares, you may need to add a proper probe_mask option
to avoid the "azx_get_response timeout" problem above, instead.
This occurs when the access to non-existing or non-working codec slot
(likely a modem one) causes a stall of the communication via HD-audio
bus. You can see which codec slots are probed by enabling
CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
proc files. Then limit the slots to probe by probe_mask option.
For example, probe_mask=1 means to probe only the first slot, and
probe_mask=4 means only the third slot.
The power-management is supported.
Quindi:
-
Il riconoscimento ad opera dei servizi kernel punta ad una MCP67
-
Il riconoscimento ad opera di ALSA punta ad una ALC 861 oppure ad ALC861VD
-
Le notizie Asus, riferite al portatile modello F5N, dicono ALC660 oppure ALC660VD
-
cosa possiamo fare in questa situazione ?:
a. individuare con precisione il tipo ALC 861 o AlC660 per poi provare un numero di combinazioni ridotto per il settaggio del modulo kernel corrispondente
b. individuare con precisione il tipo di scheda e compilare, dopo avere applicato patch opportuna, i moduli Alsa
c. individuare con precisione il tipo di scheda e compilare il kernel ( Ultima spiaggia)
-
Come vedi la condizione necessaria è sapere che tipo di scheda è quella presente nel portatile.
-
abbiamo cominciato dal punto a), ma non mi va di eseguire tanti tentativi alla cieca.
Abbiamo fatto tre tentativi tutti andati a vuoto, ed erano quelli più sensati.
Dovremmo ripeterli, eliminando pulseaudio, le utility audio dell’interfaccia grafica etc.
Dovremmo ripeterli usando lo scheletro nudo di Alsa e la linea di comando per evitare che altri software si frappongano tra noi e il modulo.
Ma questo lo possiamo fare solo dopo che abbiamo una qualche certezza rispetto al tipo di chip della scheda.
Ecco perché ti faccio tante domande se ha 2, 4, 6 canali, sto cercando di capire cosa c’è dentro.
