Hello, First of all, sorry if my English grammar is bad i'm not native English speaker. I have Arch Linux that is currently running kernel version 3.5.4 and PCIe sound card card Creative SoundBlaster Recon3D (1102:0012), which is based on Creative SoundCore3D chip (aka CA0132 which is also name used in kernel). Supposedly "basic" support for this card has been added to ALSA in kernel 3.5 and yes, it seems to detect this card and load right modules: **** List of PLAYBACK Hardware Devices **** card 0: Creative [HDA Creative], device 0: CA0132 Analog [CA0132 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 But it seems to not function right. At first there no sound at beginning music or video plays silently... but on random moment the random sequenced blipy noise is played which loops only when you play some audio, it stops when i hit stop and does back when i hit play on any application. The sequence of noise is the same on all applications and sometimes changes. After a while i realized this noise is looping buffer with some random data appearing, sitting there and sometimes changing, since when i started to playing with buffer lengths the loop of a noise gone longer when i made buffer larger. It seems that sound data lands in wrong place.... but i don't know, that just my thinking, i don't know how inside works of ALSA. So the question is, it's me (eventually distribution maintainers) doing something wrong or it's caused by premature state of support of the card by ALSA? If first case then what should i do to fix this problem? but if 2nd case is a problem then i'm always happy to provide any data from that card which would be helpful to fix this, if it's possible. I read up this chip support (CA0132) originally been added for motherboards like Gigabyte G1.Sniper M3 which use this chip for integrated sound and read that people actually getting correct sound from it, i didn't able google anyone trying to run SB Recon3D after 3.5 kernel. Also worth mention that i compiled 3.6-rc5 kernel to check if support gone any better, but there i didn't get any sound at all (maybe i didn't play audio long enough?), i only had pop in speakers when i first played the audio. So any help will be appreciated. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
