Tarjeta de sonido PCI
Hola lista,
Hace unos días realicé la misma pregunta a la lista pero como no obtuve
respuestas que me lo solucionaran y el problema persiste, ¡ahí va eso!.
Tengo una SoundBlaster PCI64 y el kernel 2.1.125 con todo puesto para que
funcione el sonido para SB 100% compatibles y el sonido no me tira. Al
ejecutar cualquier aplicación de sonido aparece el mensaje "/dev/dsp no
configurado".
En /proc/pci he descubierto que en dispositivos encontrados dice:
Bus 0, device 11, function 0:
Multimedia audio controller: Ensoniq AudioPCI (rev 0).
Slow devsel. IRQ a. Master Capable. Latency=32. Min Gnt=12.Max
Lat=128.
I/O at 0xd000 [0xd001].
Adjunto tanto los mensajes de dmesg como otros que puedan aclarar el estado
de mi sistema en el fichero snd_config.txt.
Si hago un "make xconfig", en la sección sound existe las opciones:
Ensoniq AudioPCI (ES1370)
Creative Ensoniq AudioPCI 97 (ES1371)
pero no me deja seleccionarlas. Parece que son las opciones que necesito
pues
leyendo el help de la ES1370 dice:
"Say Y or M if you have a PCI sound card utilizing the Ensoniq ES1370
chipset, such as Ensoniq's Audio PCI (non-97). To find out if your sound
card uses an ES1370 without removing your computer's cover, use lspci -n and
look the PCI ID 1274:5000. Since Ensoniq was bought by Creative Labs, Sound
Blaster 64/PCI models are either ES1370 or 1371 based. This driver differs
slightly from OSS/Free, so PLEASE READ Documentation/sound/es1370."
y si leo el de la ES1371 dice exactamente lo mismo pero referido al chip
1371.
Tras leer Documentation/sound/es1370 y Documentation/sound/es1371 (que
también adjunto: es1370.txt, es1371.txt) y no aclararme absolutamente nada,
pido por favor al que pueda ayudarme, que me eche un cable pues estoy
perdido.
Perdón por el rollo y gracias,
Javi

ALaw/uLaw sample formats
------------------------
This driver does not support the ALaw/uLaw sample formats.
ALaw is the default mode when opening a sound device
using OSS/Free. The reason for the lack of support is
that the hardware does not support these formats, and adding
conversion routines to the kernel would lead to very ugly
code in the presence of the mmap interface to the driver.
And since xquake uses mmap, mmap is considered important :-)
and no sane application uses ALaw/uLaw these days anyway.
In short, playing a Sun .au file as follows:
cat my_file.au > /dev/dsp
does not work. Instead, you may use the play script from
Chris Bagwell's sox-12.14 package (available from the URL
below) to play many different audio file formats.
The script automatically determines the audio format
and does do audio conversions if necessary.
http://home.sprynet.com/sprynet/cbagwell/projects.html
Blocking vs. nonblocking IO
---------------------------
Unlike OSS/Free this driver honours the O_NONBLOCK file flag
not only during open, but also during read and write.
This is an effort to make the sound driver interface more
regular. Timidity has problems with this; a patch
is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
(Timidity patched will also run on OSS/Free).
MIDI UART
---------
The driver supports a simple MIDI UART interface, with
no ioctl's supported.
MIDI synthesizer
----------------
This soundcard does not have any hardware MIDI synthesizer;
MIDI synthesis has to be done in software. To allow this
the driver/soundcard supports two PCM (/dev/dsp) interfaces.
The second one goes to the mixer "synth" setting and supports
only a limited set of sampling rates (44100, 22050, 11025, 5512).
By setting lineout to 1 on the driver command line
(eg. insmod es1370 lineout=1) it is even possible on some
cards to convert the LINEIN jack into a second LINEOUT jack, thus
making it possible to output four independent audio channels!
There is a freely available software package that allows
MIDI file playback on this soundcard called Timidity.
