Hi all,
My problem is that when I set channel output to "Analog output surround 5.1" (or 2.1 or 4.1), I hear no sound in front speakers, but in case of 5.1 or 4.1 I can hear sound in rear speakers. I use kernel 3.19.5 and it didn't happen in earlier kernels that is 3.18 and in 3.17 for sure.
My configuration is: OS: Fedora 21 64 bit SoundCard: ALC888 Model name: acer-aspire-4930g Laptop: Acer Aspire 5930g Speakers: external 5.1 with 3 jacks Sound channel configuration module is standard configuration module from KDE.
Additional info:
- When channel output is 5.1 and I unplug green jack and leave two others
jacks connected then I can hear sound in laptop internal speakers. 2) Earlier (kernel 3.18 and 3.17) I didn't have possibility to choose 2.1 configuration and additionally to 4.1 configuration I could also choose 4.0 configuration.
Thanks for looking into problem.
I don't remember any relevant change... Could you try git bisect?
thanks,
Takashi
