Heloo I just bought a Roland Edirol PC-80 MIDI controller and found out
that it was not supported on LINUX. I looked on the web and found
the /usr/src/alsa/alsa-driver-xxx/usbquirks.h file to be the place to
change some code to support it.
I have tried many things but I don't enough info to get it right once
and for all.
Here is what I did :
{
/* PC-80 Wave */
USB_DEVICE(0x0582, 0x0092),
.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
/* .vendor_name = "EDIROL", */
/* .product_name = "PC-80", */
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 0,
.type = QUIRK_AUDIO_EDIROL_UAXX
},
{
.ifnum = 1,
.type = QUIRK_AUDIO_FIXED_ENDPOINT,
.data = & (const struct audioformat) {
.format = SNDRV_PCM_FORMAT_S24_3LE,
.channels = 2,
.iface = 0,
.altsetting = 1,
.altset_idx = 1,
.attributes = 0,
.endpoint = 0x81,
.ep_attr = 0x01,
.rates = SNDRV_PCM_RATE_CONTINUOUS,
.rate_min = 48000,
.rate_max = 48000, //(96?)
}
},
{
.ifnum = 2,
.type = QUIRK_MIDI_FIXED_ENDPOINT,
.data = & (const struct snd_usb_midi_endpoint_info) {
.out_cables = 0x0007,
.in_cables = 0x0007
}
},
{
.ifnum = -1
}
}
}
What I got working is the audio out but cannot have the audio working.
Is there some resources somewhere that I could read to understand what I
need to do?
Thank you, Alain Lauzon
