[alsa-devel] Bad sound quality
Hi,
In linux compared to windows the sound quality is much worse. I have tried different sound cards, different distributions during past 3 years and the sound is still not good. In linux the sound is somewhat towards mids, less bass and is overall dirtier compared to windows (xp or 7). Problem is not driver specific as I have tried different sound cards on different computers. I can hear the difference even on laptop speakers. When using jack server sounds is little better, but still no way same as in windows. For me it is major obstacle not using linux as I would love to, because I listen to music so much with quality hifi system.
Sound cards which were tested are: onboard VIA, onboard Intel ACL889, Sound Blaster Live, Echo Gina20.
Thank. Standa

Is this some kind of trolling? Please record the output of the same signal at unity gain under Linux and Windows, preferrably via a digital connection, align the streams and check for any differences, especially in the resulting spectra.
It might be possible there's some poor resampling or erroneous datatype conversion in your signal chain, probably in userspace. This would explain why it occurs on all your cards.
What you can try: playback of a lossless (read: wav, flac) file directly to ALSA without dmix, pulseaudio, phonon or whatever. This is your baseline for comparison. If this "really sounds worse than Windows" (I could hardly type this undifferentiated phrase), then it's some DSP code on the Windows side.
