After I add the ppa:diwic/hda, install the hda-jack-retask and snd-hda- tools, I tried to run the command in the terminal:
hda-jack-sense-test -a I got this result from terminal: Traceback (most recent call last): File "/usr/bin/hda-jack-sense-test", line 47, in <module> codec = HDACodec(cardindex, codecindex) File "/usr/share/snd-hda-tools/hda_codec.py", line 1023, in __init__ self.fd = os.open("/dev/snd/hwC%sD%s" % (card, device), os.O_RDWR) OSError: [Errno 13] Permission denied: '/dev/snd/hwC0D0' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1252212 Title: [MS-7697, Realtek ALC887-VD, Green Line Out, Rear] Background noise or low volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1252212/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
