hda-intel: low volume with nvidia mcp7a hdmi

[Halim Sahin]

Hello,
The volume of the mentioned card is really too low.
used kernel: 2.6.31-rc6 from opensuse factory.
lspci reports:

I didn't give any cmdline params to snd-ihda-intel.
Any ideas how to get more power out of this card?

Hi,
head -n 1 /proc/asound/card0/codec* gives:

==> /proc/asound/card0/codec#0 <==
Codec: Realtek ALC662 rev1

==> /proc/asound/card0/codec#3 <==
Codec: Nvidia MCP7A HDMI

maybe this helps to understand the problem?

Regards
Halim

Not really :)

Please run alsa-info.sh (with --no-upload option), and attach
the generated file, in order to analyze more.

Also, be a bit more specific about the problem.  Which output is low
exactly?  Is it a headphone output, a built-in speaker output, or
what?  And, what is the device?  Is it a laptop, a desktop, whatever,
from which hardware vendor/product?


thanks,

Takashi
