How to build a kernel on a Parallela board

Shodruky,

I'm having no luck with usb sound on my headset. I modified my .asoundrc to be the above file and I got "Cannot open default device" (or similar). Do I need to do anything else to use it?

I've got a Logitech head set connected to my hub and lsusb (which is now working!) shows it as device 5. I work mainly headless so I'd like to use my usb phones for sound.

Your HDMI version of this file works fine. I've gotten sound from vlc and SMPlayer.

I've tried alsaconf that most sites mention but that is not found. alsa-base is installed and up-to-date.

nick,

What is the product name of your headset?

and post the outputs of these commands.

$ lsusb
$ cat /proc/asound/cards
$ cat /proc/asound/devices
$ cat /proc/asound/pcm
$ cat /proc/asound/timers

What is the output of this command:

$ lsusb -v -d 046d:0a0c

reconnect the USB audio, then

$ tail -n 20 /var/log/syslog

Sorry, one more...

$ zcat /proc/config.gz | grep SND

It seems that your kernel doesn't support USB audio driver.
Are you using current kernel source and rebuilt it?
Also we have to enable USB audio driver with menuconfig.

# e.g. enable USB sound adapter
# Device Drivers->Sound card support->Advanced Linux Sound Architecture->USB sound devices->USB Audio/MIDI driver[*] (Press Y), Save, Exit

We should be able to see these options in a properly configured kernel.

CONFIG_SND_USB=y
CONFIG_SND_USB_AUDIO=y
