Hello. This is with Gentoo, kernel 3.10.7, alsa-lib 1.0.27.2. The sound card is: # /usr/sbin/lspci 00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) and aplay -L gives # aplay -L sysdefault:CARD=PCH HDA Intel PCH, ID 269 Analog Default Audio Device When I play an audio file, the sound comes out on the internal speaker. The 3.5mm jack connector is a 4-pole one, it embeds both speakers and microphone. If I connect a standard, 3-pole headphone on it, the sound comes out hissing as if some medium frequencies were left out. The sibilants (esses) are especially hard to bear, and the audio sounds 'hollow'. Is a know problem of the driver, or is my hardware at fault? I can't test on windows since I had to erase it from the HD to be reimbursed from the cost of the licence by Asus. Thanks for any info. ------------------------------------------------------------------------------ Introducing Performance Central, a new site from SourceForge and AppDynamics.
