[alsa-devel] [PATCH 1/2] ASoC: wm9081: Fix reading wrong register for setting VMID 2*240k

by ajay khandelwal 08 Nov '11

08 Nov '11

Hi all, I have a pc with SPDIF out. I want to play audio file with single channel(mono) using aplay. How to do that, when I try to play with following command, it gives error aplay -Diec958:CARDICH6,DEV=0 mono_music.wav it gives following error aplay: set_param:1065: Channels count not available. Thanks and Regards, Ajay

[alsa-devel] Swapped channels issue on pxa-ssp based platforms
by Daniel Mack 08 Nov '11

08 Nov '11

Hi, we're hunting a weird bug on PXA3xx/ssp based audio devices which causes the playback channels to be swapped when the capture stream is started at the same time. Content for the left channel appears on the right and vice versa, in approximately 50% of all test runs of the following command: $ arecord -f cd - -D hw:0,0 | aplay -D hw:0,0 -f cd - When just aplay is used, everything's fine. It's unrelated to the codec part, as we see this with machines that feature different models. I guess this is some sort of a race condition in the stream startup, and suspected sound/soc/pxa/pxa-ssp.c to lack some locking, so I added a spinlock around all register read-modify-write cycles. But that doesn't seem to be the reason. It could also be the DMA engine that writes to the wrong position, but I fail to see it right now. Does anyone have an idea where to look for the culprit? Have there been similar effects in other SoC platforms? Thanks for sharing your thoughts :) Daniel
