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
