Hello again,
To continue on the debugging of the Duo with the SiS chipset.
I have now installed the CVS version of alsa.
once I load all of the modules, I get no errors.
When I try to play a sound, I get the following from dmesg :
ALSA usbaudio.c:686: cannot submit datapipe for urb 0, err = -22
I turn off the usb device and unload all of the alsa modules. I then
turn on the device and get the following :
usb.c: USB disconnect on device 00:03.0-1 address 3
usb.c: deregistering driver audio
usb.c: deregistering driver snd-usb-audio
hub.c: new USB device 00:03.0-1, assigned address 4
usb.c: USB device 4 (vend/prod 0x763/0x2002) is not claimed by any
active driver.
usb.c: registered new driver snd-usb-audio
usb.c: registered new driver audio
audio.c: v1.0.0:USB Audio Class driver
All looks good.
I then try to aplayt a wav file and again get the following :
ALSA usbaudio.c:686: cannot submit datapipe for urb 0, err = -22
Which corresponds to the following block of code (usbaudio.c):
subs->running = 1;
for (i = 0; i < subs->nurbs; i++) {
if ((err = usb_submit_urb(subs->dataurb[i].urb,
GFP_KERNEL)) < 0) {
snd_printk(KERN_ERR "cannot submit datapipe for
urb %d, err = %d\n", i, err);
goto __error;
}
set_bit(i, &subs->active_mask);
}
