Ah, I thought you already added my repository, my bad. Pablo's link will bring you to a Wiki page explaining how to add the repository.

Thanks AutoStatic and Pablo, I am success to install madfuload . but still doesnt work.

Code: Select all

[madfuload
Please specify a firmware file.
/code] 

[code]aplay -l

Could you do a:

Code: Select all

tail -f /var/log/syslog

with the M-Audio Micro not connected and then connect it? Does the log show anything? Could you post that?
The lsusb output in your case doesn't show any references to 'DFU' though so I highly doubt the current firmware loaders can handle your interface. If it needs any firmware at all.

autostatic · Post by **autostatic** » Tue May 21, 2013 1:24 pm

I don't think it will work. The M-Audio Micro is also a dongle for the Session software so it's probably a Windows only device.

I suggest you ask in the alsa users mailing list [1], [2]. Hopefully one of he alsa devs (driver programmers) can help you, or at least, give you a definitive answer. You will have to suscribe first

In your e-mail, post the output of:

lsusb -v -d 0763:201a

So madfuload gets called but then fails because of an out of memory error. On the one side this is hopeful (madfuload gets triggered), on the other hand, how to get around the memory error? Just a shot in the dark, could you try:

Code: Select all

sudo mount -o remount,size=128M /dev/shm

and then insert the Micro again?

Thanks Autostatic I will try sudo mount -o remount,size=128M /dev/shm and report result as soon possible. other guys from alsa user mailing list tell Me about The device needs a quirk in order to be recognized by snd_usb_audio with add entry on quirks-table.h but I dont know how to do that?. I must add the entry to the file sound/usb/quirks-table.h but I cant found a folder sound/usb/, would you tell Me about that? here quirks-table.h

Code: Select all

{
        USB_DEVICE(0x0763, 0x201a),
        .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
                /* .vendor_name = "M-Audio", */
                /* .product_name = "Micro", */
                .ifnum = QUIRK_ANY_INTERFACE,
                .type = QUIRK_COMPOSITE,
                .data = & (const struct snd_usb_audio_quirk[]) {
                        {
                                /* Control device */
                                .ifnum = 0,
                                .type = QUIRK_IGNORE_INTERFACE
                        },
                        {

                        }
                }
        }
},

So today I starting to using on board audio and installing jack but not sucessfull how to install jack on raspberry , I am using your repository and confuse with patch jack

You need to modify the source of the USB sound driver so you have to download the RPi kernel source, modify quirks-table.h and recompile your kernel (or just the snd-usb-audio module itself).

My repository contains patched JACK versions that work on the Raspberry Pi. The JACK packages from the standard Raspbian repositories do not work. To use JACK with the onboard audio you need a fully updated Raspbian installation with the latest firmware and then you'll find out that the onboard audio really isn't made for real-time, low-latency audio. At least, I can't get it to work properly with JACK.

Thanks installing M-audio micro is getting complicated and make me crazy, so I am doing make a fresh install raspibian and change soundcard using E-MU 0202, now raspberry can detect E-MU

Code: Select all

/code]
I following AutoStatic step on http://wiki.linuxaudio.org/wiki/raspber ... repository. I try follow instruction, please correct me if I making mistake?
1) make Setting the default soundcard
[#options snd-usb-audio index=-2/code]
2) add repository
wget -O - http://rpi.autostatic.com/autostatic.gpg.key| sudo apt-key add -
sudo wget -O /etc/apt/sources.list.d/autostatic-audio-raspbian.list http://rpi.autostatic.com/autostatic-au ... pbian.list
sudo apt-get update
3)Patching Jack but I dont know to do that? would you give me how to patching Jack?
4) installing package jack 2
sudo apt-get --no-install-recommends install jackd2
5) running Jack
sudo mount -o remount,size=128M /dev/shm
echo -n performance \
| sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
6) using external sound card
how to configuration jack command with E-Mu 0202 ? I am also still confuse.

-dhw:E-MU 0202

This should be -dhw:USB

You don't need to patch JACK, patched JACK packages are in my repository. I'll change this in the Wiki to make it clear you don't have to patch anything yourself when using my repository.

pukulsesuatu wrote:Cannot lock down 13589216 byte memory area (Cannot allocate memory)

You have to select 'Yes' when the JACK install asks if you want to enable real-time priorities. Please run sudo dpkg-reconfigure jackd2 and select 'Yes'. I'll add this step to the Wiki too.

Great! aplay doesn't work with JACK. You need a player that supports JACK like Aqualung.
