[alsa-devel] [PATCH] WM8750: Convert to new API
by Marek Vasut 08 Apr '10

08 Apr '10

Register the WM8750 as a SPI or I2C device. This patch mostly shuffles code around. Hugely inspired by WM8753 which was already converted.

[alsa-devel] User-space control elements in ext PCM plugin
by Marcus Weigelt 07 Apr '10

07 Apr '10

Hi, I´m having an external PCM plugin that should do some processing on the audio. That part works fine. Now I´d like to have some way to modify the way to give some parameters to the plugin to tell it how the processing is done (eg. set delay time, pan, attack time, ...). I´ve searched the web for days and hours, but could not really find something. On the alsa mailing list there was a similiar question three years ago, and the answer was, that one could create user-space control elements in the plugin. How is that done? I could not find examples or good documentation about it. Did I miss something out? Can anyone give me a hint, maybe a link to some docs about it or source of a PCM plugin creating/using user space control elements? Thanks a lot.

You need to write your own gadget driver for that. See the ones that already exist in the tree and see which parts you can recycle for your purpose. The protocol you want to talk is HID.

[alsa-devel] ali5451 - no sound after resuming from suspend
by Rami Autiomäki 07 Apr '10

07 Apr '10

Hello, My laptop suspends and resumes find, but sound is not working after computer is suspended and resumed. I can fix sound by running as root "alsa force-reload". This bug has been some time ago reported to alsa bug tracker: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=959 I compiled vanilla kernel 2.6.33.2 from kernel.org, after suspending sound fails similarly with this kernel also. I looked my alsa-info logs (they are somewhere down there) before and after suspend, and files differ much at where it says "Current setup". -- Rami Autiomäki -- Package-specific info: ** Version: Linux version 2.6.32-3-686 (Debian 2.6.32-9) (maks(a)debian.org) (gcc version 4.3.4 (Debian 4.3.4-8) ) #1 SMP Thu Feb 25 06:14:20 UTC 2010 ** Command line: BOOT_IMAGE=/boot/vmlinuz-2.6.32-3-686 root=UUID=d58ac20c-4ecb-4cc6-91b5-acad8448af76 ro quiet noapic nolapic ** Tainted: P (1) * Proprietary module has been loaded. ** Kernel log: [ 732.060050] ali_stimer_read: stimer is not ready.

[PATCH] ALSA: usb/caiaq: use usb_buffer_alloc()
by Daniel Mack 06 Apr '10

06 Apr '10

Use usb_buffer_alloc() and usb_buffer_free() for transfer buffers. We need DMA-coherent memory in this case as buffer contents are likely to be modified after the URB was submitted, because the URB buffers are mapped to the audio streams. On x86_64, buffers allocated with kmalloc() may be beyond the boundaries of 32bit accessible memory, and DMA bounce buffers will live at other locations, unaccessible by the driver, and hence outside of the audio buffer mapping.
