* [PATCH] ALSA: usb-audio: allow -EPIPE errors for some v2 messages @ 2021-10-10 12:22 Greg Kroah-Hartman 2021-10-10 20:25 ` Takashi Iwai 0 siblings, 1 reply; 12+ messages in thread From: Greg Kroah-Hartman @ 2021-10-10 12:22 UTC (permalink / raw) To: Jaroslav Kysela, Takashi Iwai; +Cc: alsa-devel, linux-usb, linux-kernel The Schiit Hel device does not like to respond to all get_ctl_value_v2() requests for some reason. This used to work in older kernels, but now with more strict checking, this failure causes the device to fail to work. Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> --- This fixes the Shiit Hel device that I have. It used to work on older kernels (a year ago?), but stopped working for some reason and I didn't take the time to track it down. This change fixes the issue for me, but feels wrong for some reason. At least now I can use the device as a headphone driver, much better than the built-in one for my current machine... If needed, I can take the time to do bisection to track down the real issue here, it might be due to stricter endpoint checking in the USB core, but that feels wrong somehow. Here's the debugfs USB output for this device, showing the endpoints: T: Bus=07 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 5 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=30be ProdID=0101 Rev=01.02 S: Manufacturer=Schiit Audio S: Product=Schiit Hel C: #Ifs= 4 Cfg#= 1 Atr=c0 MxPwr=0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=01(audio) Sub=01 Prot=20 Driver=snd-usb-audio E: Ad=8f(I) Atr=03(Int.)

This should be persistent and visible; try to run "amixer -c1" (or the different card index for the device). So far, so good. The only remaining piece is how this -EPIPE error comes up. Is this a protocol stall error or such? Would it be avoided by adding the delay like done for some devices? With the 5.15-rc kernel, you can pass quirk_flags option to snd-usb-audio module for applying known quirks. e.g. quirk_flags=0x100 will set the 1msec delay at each control message. Please check whether it makes any difference. The option is an integer array for multiple devices, so if you have multiple USB-audio devices, put at the appropriate position in the array (e.g. quirk_flags=,,0x100 for the 3rd slot). The quirk bit 0x4000 will shut up the control errors. If the above doesn't fix the warning and the device is working more or less, set this quirk to shut up the warning. It can be set statically in the table at the end in sound/usb/quirks.c. Takashi ^ permalink raw reply [flat|nested] 12+ messages in thread

OK, thanks! The remaining error message should be suppressed with the patch in my previous mail.
