[alsa-devel] hda-intel: low volume with nvidia mcp7a hdmi
Hello, The volume of the mentioned card is really too low. used kernel: 2.6.31-rc6 from opensuse factory. lspci reports: 00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1) Subsystem: nVidia Corporation Device cb84 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Ste Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- Latency: 0 (500ns min, 1250ns max) Interrupt: pin A routed to IRQ 21 Region 0: Memory at fad78000 (32-bit, non-prefetchable) [size=16K] Capabilities: [44] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3ho Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: HDA Intel

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