[alsa-devel] aplay lists both Playback and Capture devices
by Fabio Estevam 02 Jun '13

Hi, When running 'aplay -l' and 'arecord -l' I see the following output on a mx28evk running a 3.10-rc kernel: /$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: mxssgtl5000 [mxs_sgtl5000], device 0: Playback sgtl5000-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: mxssgtl5000 [mxs_sgtl5000], device 1: Capture sgtl5000-1 [] Subdevices: 1/1 Subdevice #0: subdevice #0 $ arecord -l **** List of CAPTURE Hardware Devices **** card 0: mxssgtl5000 [mxs_sgtl5000], device 0: Playback sgtl5000-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: mxssgtl5000 [mxs_sgtl5000], device 1: Capture sgtl5000-1 [] Subdevices: 1/1 Subdevice #0: subdevice #0 I would expect to see only the Playback entry in aplay and only the Record entry in arecord. Is there anything I should change in sound/soc/mxs/mxs-sgtl5000.c in order to get the correct outputs? Regards, Fabio Estevam

[alsa-devel] [PATCH 1/2] dma: Add a PAUSE_RESUME capability
by Lars-Peter Clausen 01 Jun '13

01 Jun '13

Add a capability which allows dmaengine consumers to query whether a dmaengine controller supports the DMA_PAUSE and DMA_RESUME commands. Sometimes a user of the dmaengine API needs to know in advance if a channel will support pause/resume. E.g. in ALSA the information whether it is possible to pause/resume a audio stream or whether it is necessary to abort and restart the stream is communicated to userspace so it can act accordingly.

Actuvally I added samsung prefix when I added s5pv210 compatible name. But I also feel Exynos would be better now. I will resend the patch with Exynos prefix and with your reviewed-by.
