[alsa-devel] [patch] Add a software amplifier plugin
Hi.
Most of the modern built-in cards do not have an internal amplifier. This makes it difficult to use them with those cheap small passive speakers that were in a heavy use 15 years ago when the cards had an amplifier builtin. I wrote a simple software amplifier plugin, it is attached. Of course you trade a sound quality, but whoever uses the passive speakers, have already made his choice anyway.
Would it be possible to apply such a patch to the repository?

Did you try the recent softvol plugin? It supports already amplifier (> 0dB), not only attenuation.
thanks,

Yep, I tried it for the whole day with alsa-lib-1.0.14, trying to feed it with the max_dB value to no avail.

Oh, it does so only in hg, not in 1.0.14, now I see. Well, it seems to me that my plugin gives a way better quality (doing sine amplification, while yours probably does linear), but then yes, there is no point for the new plugin indeed.
