Hallo all, Takashi,
there is one regression in current linux main tree:
cval->res quirks do not work any more. See usb/mixer.c:1150 Are there was some work in this area or may be some one bisected this bug down?
Are you referring to the device 046d:09a4, which sets the mixer range manually? If yes, does the patch below work?
No, i referring to devices 046d:0991, 046d:081d, i don't have access to 046d:09a4.
This part is broken for me: case USB_ID(0x046d, 0x0991): /* Most audio usb devices lie about volume resolution. * Most Logitech webcams have res = 384. * Proboly there is some logitech magic behind this number --fishor */ if (!strcmp(kctl->id.name, "Mic Capture Volume")) { snd_printk(KERN_INFO "set resolution quirk: cval->res = 384\n"); cval->res = 384; } break;
OK, so _what_ is actually broken? Do you see the message but cval->res is overridden later?
yes.
To which value?
Also you should have got a message like "0:1: cannot get min/max values for ..." when built with CONFIG_SND_DEBUG. Check whether you get it actually.
