Mono output Band-Pass Filter For many applications, the primary speakers are incapable of reproducing low frequency audio. Therefore it is desirable to implement a woofer or sub-woofer speaker. The mono output is ideal for this task. However, the frequency response should be restricted to prevent interference with the primary speakers. Typically an external filter, known as a cross-over filter, is used. The mono processing path includes a band-pass filter with programmable high and low cut-off frequencies to eliminate the need for an external filter. 2.3.1. Mixer Filter Description The band-pass filter is derived from the common biquadratic filter and provides a 12dB/octave roll-off. The filter may be programmed for a -3dB lower band edge of: 63Hz, 80Hz, 100Hz, 120Hz, 150Hz, 200Hz, 315Hz, or 400Hz. The filter may be programmed for a -3dB upper band edge of: 150Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, or 800Hz. The band-pass filter is enabled by default with a cut-off frequencies at 120Hz and 250Hz. The filter may be bypassed using the associated verb (processing state verb

And do you know how to control those equalizer filters with software or do you know where we can find the detailed document for this part?

I am not sure about it, but enable/disable the SW lfe filter will make the sound of subwoofer different > _______________________________________________ > Alsa-devel mailing list > Alsa-devel@alsa-project.org > http://mailman.alsa-project.org/mailman/listinfo/alsa-devel > >

I am trying to enable the subwoofer speaker on a HP laptop, on this machine, there are two speakers and one headphone, but the BIOS verb only enabled one speaker(nid 0xd) and one headphone(nid 0xb), I need to use quirk in the kernel driver to configure the second speaker (subwoofer speaker, nid 0x10). Under current alsa driver, the headphone will be assigned a dac (nid 0x13) and the 2 speakers will be assigned a dac (nid 0x14), this assignment is not good since 2 speakers share the same dac, this means 2 speakers can't work at the same time to support 4.0/2.1 channels. On another Dell machine with realtek codec, there are also 2 speakers, 1 headphone and 2 dacs, on this machine, 1 speaker and 1 headphone are assigned 1 dac, and the other speaker is assigned another dac, so there is no problem for this machine to support 4.0/2.1 channels. Through debugging, I found on Dell machine, the speaker nid only has one connection to dac (hardwired), so when driver assign dac to it, the map_single() can successfully assign the each dac to the 2 speakers respectively. But on that HP machine, the speaker has multiple connections for dac, the map_single() can't work for this machine. The alsa-info.txt for that HP machine is at http://pastebin.ubuntu.com/11667947/ The alsa-info.txt for that Dell machine is at http://pastebin.ubuntu.com/11667982/ To fix this problem, I can use the quirk in the driver to make the speaker have only one connection for dac or do some change in the hda_generic.c like below, in your opinion, which one is better or probably you have a different idea to fix this problem?
