New sound device question

New sound device question

[Laurent Epinat]

Hello All

I'm a newbie in this group and the sound systems.

I try to developpe a usb sound driver for a Alesis Multix 8 USB2.0

http://www.alesis.com/multimix8usb20

The output interface is allready fonctional, but the Input not :-(
Because there is 2 end point for it. The first one is on Isochronous 
mode and the other is on Bulk mode

I don't know how to declare the second endpoint in the quirks_table.


Where can I get a good documentation or help about the alsa USB sound 
structure.

The only informations I have about the devices, are dump from windows


thanks

There is no predefined quirk for such an endpoint; you'd have to write
your own code.

At the moment, the only documentation is the source code.

What is the bulk endpoint used for?

Intel-HDA Realtek Codec // double matching PCI IDs

[Thomas Wagner]

Hello there,

I am in trouble with Sound on my Asus N53Jf Notebook.
Full Story at : https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5188


Raymond noticed that My and the ASUS N63Jn share the same PCI ID.
Forcing ALSA to BIOS autoprobe is my current workaround.
The PCI QUIRK for N63Jn spoils the Autodetect for my N53Jf.


Second Issue the "Subwoofer" isn´t connected.

I think it´s like the

          ALC269_FIXUP_ASUS_G73JW


I didn´t find a way to seperate both Hardware behaviours...
Or is it an mistake ?

Maybe someone give me an hint?
Through the code I can´t understand the whole design/Structure.


Sorry,
    Thomas

I don't know exactly,
I think the Isochrone endpoint is used for control and the bulk one is 
the data, because the size is bigger and the interval is short than the 
isochrone one

on the device you can record 10 inputs channels at the same time
