Greetings, I have bourght a Asus Xonar SE (90YA00T0-M0UA00) which is only working partially. While the rear connectors seems to work the front header is not. I found some reports scattered around the internet with the same issue but without a solution. It is a PCIe card with an pcie-to-usb interface. Thus the card is reported as a usb device: ID 0b05:189d ASUSTek Computer, Inc. Xonar SoundCard The card has several audio Endpoints EP 5 to EP 9 and an additonal HID EP 4. All the rear connectors seems to work. Can't test the SPDIF but found a SE specfic quirk in the alsa USB configuration for the SDPIF PCM thus assume this issue was already fixed. EP 5 -> Audio Out EP 6 -> SDPIF EP 8 -> Line In The rear connector don't have a plug-in-detector, the front-panel has and is working: node hw:1, #16 (0,0,0,Headphone - Output Jack,0) VALUE node hw:1, #31 (0,0,0,Mic - Input Jack,1) VALUE In stereo configuration the card has "headphones" and "speaker". The Front Panel input nor output is working. If headphones is selected the rear is disabled but the front header is not working. Side note the default Microsoft driver has the same issue so I assume the card usb configuration is faulty. I installed the ASUS driver and tracked the USB messages with wireshark in a Windows VM. I noticed the Asus driver uses those additional posts EP 7 -> Front Audio Out EP 9 -> Front Audio In Neither the default Windows, nor alsa use those EP. Is there a way to force the alsa driver to use EP7/9 to further analyse this issue? Best Regards Smesgr Sent with ProtonMail Secure Email.
