[Kernel-packages] [Bug 1721987] Re: No sound from right audio channel
It never ceases to amaze me how collectively we manage to overcome these issues. Yes, your wantedby list is a great addition. The left speaker is so loud I hardly noticed the lack of stereo after waking. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1721987 Title: No sound from right audio channel Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: No audio comes out of the right speaker on the laptop.

Ok, I got it working without needing to recompile the kernel. Make sure that you have the alsa-tools installed on your machine.

After reading the Linux audio sub system documentation I discovered /sys/class/sound/hwC0D0 and hda-verb.

[Kernel-packages] [Bug 1721987] Re: No sound from right audio channel
Would there be by any chance a way to send that magic sequence through the bus using a script or tool from within the terminal? I am on Manjaro 4.19.16.1 and I was unable to recompile my kernel using the patch, replacing the c file or manually editing it. My notebook takes about 4 hours to compile the kernel, which does not help. Here is my information: http://www.alsa- project.org/db/?f=4bbd25ca31126e42e28f73c16143d1158b6eb27a PS: Wonderful work by the way. I just wished I could hack this myself into the patch_realtek.c file for Manjaro. However, I am hoping that sending the magic sequence while the machine is running might work too. I just wouldn't know how. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1721987 Title: No sound from right audio channel Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: No audio comes out of the right speaker on the laptop.
