Subject: [PATCH] [UBUNTU:sound/pci/] #68659: Disable DXS explicitly for
0x1458a002 (VIA-based)
UpstreamStatus: Not yet merged
References: Ubuntu: #68659, #68876
Debian: #366212
ALSA: #2067
http://hg-mirror.alsa-project.org/alsa-kernel?cs=5cf914368b6e;style=raw
As the two referenced Ubuntu bug reports testify, using VIA_DXS_SRC
by default is insufficient and results in errors such as
"Sound server fatal error: cpu overload, aborting". This patch
explicitly disables DXS for a known broken ID (despite the source
claiming it works).
This commit closes Ubuntu: #68659, #68876.
This commit is applicable to Dapper, Edgy, and Feisty linux-source.
