[Desktop-packages] [Bug 359361] Re: ALSA SPDIF Digital output clipping / crackling during playback
This affects me too.
I'm using 14.04.3 and the spdif crackles. My kernel is 3.16.0-53-generic
#72~14.04.1-Ubuntu.
I'm using a Asrock Z97 Extreme6 and a new cable. All other audio output
is fine but while getting a bit stream from USB the audio is rather
muted but usable.

Title:
ALSA SPDIF Digital output clipping / crackling during playback
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
When playing sound in Jaunty out of my HDA Intel SPDIF out, loud
sounds clip. This is audible because from the strong distortion it
produces, which I have seen some people characterize as "crackling".
For example, if I go to system->preferences->sound and play the test
sound, the sinusoid is audibly clipping. I have all of my sliders in
alsamixer zeroed except for master (@100) and IEC958 (@100). Note that
if I turn down the volume of the master and/or the IEC958, the
clipping is still present---I've gone as low as -21dB (64/100) on both
sliders simultaneously, and the clipping is still there.
I looked around for solutions, this sounds similar to my problem:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/285866
However, as I noted, I've tried reducing my levels, and my PCM mixer
level is all the way at 0 (-58.50 dB) anyway. Not to mention that
these are digital outputs, so having them at the 0dB gain position
(100% for the master and IEC958 sliders) should be fine...
Yes I am certain it's not my speakers clipping.
Oddly enough, at one point I was able to get it not to clip in the
gnome sound settings control by going through some sequence of trying
different backends (various options for ALSA, for OSS, etc.). I have
not been able to reliably reproduce the non-clipping, but I will keep
trying.
For some reason, I hear the clipping when I listen to music using
gnome-listen, but not when using Amarok using Xine as the backend.
Please help me stop the clipping.

[Desktop-packages] [Bug 1493888] Re: FGLRX incompatible with gcc 5
I'm having the same problems. I need the proprietary driver because the open source driver does not implement the computational part.

This causes the kernel module to crash on initialisation. As a result, users will boot into a black screen, as X will fail (except on Intel+AMD hybrid systems, where intel is used). [Test Case] 1. Either install (or upgrade to) Ubuntu 15.10 and fglrx 2. Reboot 3. Check the display, and the output of the "dmesg | grep fglrx" command (to see the actual crash) Expected results: the system should be able to start X correctly. Actual results: The kernel module fails and X doesn't start. [Regression Potential] Low. Forcing fglrx to use gcc 4.9 is only a temporary workaround, and will be replaced with the proper fix once AMD makes it available. __ With a R9 280 and FGLRX on ubuntu 15.10 the graphics lock up. I am able to SSH into the machine. I booted the older kernel (4.1.0-3-generic) and it works with FGLRX.
