USB Sound Card

zetrotrack000 · 07-09-2017, 04:38 AM

Hi
One of my laptops (installed with arch linux) has a non-repairable faulty audio jack, so I use USB sound card in order use a headphone. However, sometimes suddenly the system freezes and I have to hard reset it. Journalctl is showing following error:

Code:

Although I am unfamiliar to these errors but one thing that I am sure about is that the problem is happening due USB. Kindly help me to solve this problem.
Regards

There are some old posts with the same error, which may (or may not) provide a solution

At least they offer some starting points to explore: bad cable, wrong sort of USB port, mysterious command to use, etc.

These posts are very old and talking about USB 1.1 and USB 2.0. However, my laptop has USB 3.0 and the sound card is also new (bought 4 months ago). Here is the output of lsusb:

Code:

Bus 003 Device 002: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller

Are these things still applicable to linux? I doubt that!

During boot, the system gives this error:

Code:

kernel: platform wdat_wdt: failed to claim resource 4: [io  0x0071-0x0072]
kernel: ACPI: watchdog: Device creation failed: -16

and this error:

Is that a sign that my hard-drive going to fail?

Can you get anything from above info, which can help me?

No, your hard drive is fine! That would be /dev/sda — /dev/sr1 is an optical drive. Do you have a disk in the drive when you boot up?

That error code on the USB device seems to be indicative of a very low-level problem: the computer finds the device unusable. Did you try using different ports, both USB2 and USB3? Have you tried the device on a different computer? I'd expect a fault in the device to show up more often, though, and it's strange that it should cause a lock-up. If the audio jack stopped working, it might be that the USB controller is about to go too.

These sort of occasional failings can be very difficult to track down. This computer crashes about once a month. After making sure the memory wasn't faulty, I decided to live with it.

No, dvdrom is empty.

This also happens if I plug/unplug USB device 3-4 times consistently.
