Red Hat Bugzilla – Bug 15519
i810 audio works, but is flaky
Last modified: 2014-03-16 22:15:35 EDT
Two main problems (this is against the -19 kernel)
1: drain_dac, dma timeout messages appear often
2: when using sox on an 8-bit mono sound, it doesn't appear
to be communicating right the lack of mono support:
sox sample.au -t ossdsp /dev/dsp
produces a really high pitched sound
sox sample.au -t ossdsp -c2 /dev/dsp (to force stereo)
produces correct output.
This defect is considered MUST-FIX for Winston Gold-release
New driver sent to the list.

(RC1) The GX150 i815 chipset. Wav plays, CD plays and MMap plays. However the
sound is low. Wav. Files are cut off when played complete wav. Does not play.
It gets better Is there a way the default sound volume setting for this device
be set higher?
The default is set fairly low because some boards are _very_loud_ when you set
it higher by default. If the board at top volume is a lot quieter than in
windows then I need to know how the external amplifier is wired to the codecs as
this might by a crystal setup with an external amplifier that is connected to
the AC97 GPIO/EAMP pins

The standard kernel works, the RH one doesnt. Looks like a patch has gone astray
or something here guys ?
If Dell wants a different default volume, you can always
ship an /etc/.aumixrc like the attached file.
