[Alsa-user] Resampling tipstricks
Hello dear all!
There are 2 sound cards on my PC: hda_intel (ALC888 from Realtek) and
SBLive 5.1
1. I could that ALSA make software resampling (44.1 to 48 kHz) when
sound playing through SBLive and do not resampling if using hda_intel.
How asoundrc must be configured in this case?
I've fund some different examples - what's the best choice?
1.1.
pcm.HQ {
type rate
slave {
pcm hw:0,0
rate 48000
}
converter samplerate_best
}
1.2.
defaults.pcm.rate_converter samplerate_best
2. In my OS (Kubuntu 10.04) installed not latest version of ALSA libs.
How I can know exactly which version of ALSA using. I mean are there any
incompatibilities between for instance 1.0.23 ver of ALSA and 1.0.24 of
alsa-lib, alsa-plugins (I have choose right version of alsa-lib,
alsa-plugins and install them).
3. Is it possible to use OSS and ALSA both? I could that hda_intel uses
ALSA, SBLive - OSS. How exactly?
Thank you in advance

Re: [Alsa-user] Acer 4820TG hda-intel wrong BIOS-autoprobing
I noticed that error messages hda-intel: spurious response hda-intel: azx_get_response timeout, switching to polling mode: ... hda_intel: azx_get_response timeout, switching to single_cmd mode are present in dmesg only when Intel integrated graphic card is used. The system has two GPUs (Intel + ATI dedicated). If ATI card is selected at boot (using vga_switcheroo) no such messages are displayed. Is there any logical explanation to this behavior? Thanks and regards, Tommaso 2011/7/27 Tommaso Falchi Delitala volalt...@gmail.com Hi everybody, I think there is something wrong with the intel-hda model autoprobing on my Acer TimelineX 4820TG. The chip is recognized as: hda_codec: ALC271X: BIOS auto-probing, but Pcwizard under Windows 7 reports it as Realtek ALC-269. Other info I found on the Internet seem to confirm 269 is the right codec. Can anybody confirm the correct model onboard the Acer 4820TG? Dmesg is populated with: hda-intel: spurious response 0x0:0x0, last cmd=0x270d80 [...] hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x00270e02 [...] hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x00170503 azx_single_send_cmd: 177 callbacks suppressed I guess these erros result from wrong model autoprobing. Audio works anyway, but occasionally lags and shows major problems after enabling powersave features. I tried to force audio model with: options snd-hda-intel model=laptop-amic probe_mask=1, or options snd-hda-intel model=acer but it doesn't work. Is there a real problem in the codec model auto-probing? Should I file a kernel bug or am I missing something in the configuration?.

[Alsa-user] From git, building ALSA fails with error caused by SND_SOC_CUSTOM is used but never declared
Good day!
I tried to build ALSA from git and SND_SOC_CUSTOM is never declared in
file alsa-kernel/soc/soc-io.c, hence the build fails with first error:
alsa-kernel/soc/soc-io.c:370:7: error: ‘SND_SOC_CUSTOM’ undeclared (first
use in this function)
Below is the actual contents of alsa-kernel/soc/soc-io.c, where it can be
verified that SND_SOC_CUSTOM is used but never declared
Please note that I am using Linux kernel 3.0.0-1 in Debian Sid.

Your machine have two HD-audio controllers, one for on-board audio and another for HDMI. HDMI looks like ATI D-GPU, and this confuses the system when GPU isn't active. It seems that HDMI controller doesn't respond when GPU is disabled. A question is whether HDMI really works when D-GPU is enabled. Did you test it?
