[Kernel-packages] [Bug 1654448] Re: Dell XPS 13 9350/9360 headphone audio hiss
Same issue as previous 3 reporters. All was fine until the latest update(s), I now have the hiss back... Any idea on what might've changed? -- 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/1654448 Title: Dell XPS 13 9350/9360 headphone audio hiss Status in Dell Sputnik: Confirmed Status in alsa-driver package in Ubuntu: Confirmed Status in linux package in Ubuntu: Won't Fix Status in pulseaudio package in Ubuntu: Confirmed Bug description: Pertaining to 16.04 on a dell XPS 13 9360 ii alsa-base 1.0.25+dfsg-0ubuntu5 Advanced Linux Sound Architecture Driver Version k4.4.0-57-generic. When headphones are plugged in, there is a clearly audible hiss (white noise). This is present as soon as the headphones are plugged in, whether 'headphones' or 'headset' are selected from the pop-up box. Using alsamixer to debug the issue reveals that it is related to "Headphone Mic Boost" - the default setting is: dB gain 0.00, 0.00. If this is changed to: 10.00, 10.00 (one notch up) the hiss disappears. 20.00, 20.00 cause a louder hiss and 30.00, 30.00 causes an even louder hiss with high frequency audio artifacts. When the headphones are removed and plugged back in the Headphone Mic Boost setting returns to dB gain 0 and the problem also returns.

[Kernel-packages] [Bug 903961] Re: Kernel regression.... boot param acpi=off now NEEDED
Is there still interest in getting this issue fixed for 32-bit? I got here via the links http://askubuntu.com/questions/204905/compaq- presario-r3000-randomly-fails-to-boot-on-11-10-12-04-12-10 and http://askubuntu.com/questions/87187/11-10-randomly-fails-to-boot-on- compaq-presario-r3000 I'm having the intermittent boot issue on a Compaq Presario R3000 now with Lubuntu 13.04. The CPU in this laptop doesn't have 64-bit extensions... acpi=off does not fix the issue. What can I provide to help debugging this issue? Thanks! -- 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/903961 Title: Kernel regression boot param acpi=off now NEEDED Status in “linux” package in Ubuntu: Expired Bug description: Currently running 10.04 and no boot param needed. WORKAROUND: From 10.10 and onward I have needed kernel parameter acpi=off Which is of course a bad idea to run a system without acpi. I have tried numerous boot parameters and none work consistantly. acpi_osi Windows 2006 (2001 SP1/SP2) worked occasionally. This affects other distros as well. Lucid puppy 5.25 works perfectly, but the current slacko puppy does not. all ubuntu derivatives are commonly affected, as well as debian. I have tried running some other live CDs of others (Arch, etc..) all with the newer kernels are affected. This is related to other bugs 626622 633596 and probably more than that. Maverick is where the issue began. I am absolutely sure it is the kernel because of running non Ubuntu OS with the later kernels and needing the param acpi=off. I would like to use the modern systems for my computer, as they have much better features, and some of the newer programs are something I really want to use.
