[alsa-devel] How to test new SDPIF implementation?
by Jon Smirl 10 May '09

10 May '09

I would like to test my SPDIF driver implementation. How can I used command line tools to play sample 5.1 music over SPDIF? I have a file 5.1 AC3 encoded file -- w.ac3 This doesn't work: iecset -D hw:0 audio off aplay -c 2 -r 48000 -f S16_BE -D hw:0,1 w.ac3 I can play uncompressed music on SDPIF without problem. I know my audio system will play the compressed music, I can use A52 from my desktop. -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] [PATCH 1/2] speaker-test: move existing endian macros up in the file
by Dan McGee 10 May '09

This is necessary for a later patch removing the various endianness checks sprinkled throughout the code.

[alsa-devel] [PATCH 3/4] pxa2xx-i2s: Cleaner use of the FIFOs
by Karl Beldan 09 May '09

09 May '09

The FIFO logic and the registers are reset at stream startup with SACR0_RST => the sibling function might suffer and the FIFOs might unpleasantly fill up whence the calls to pxa_i2s_wait all over the place. This gets rid of it.

[alsa-devel] asus xonar DX
by Dmitri Seletski 08 May '09

08 May '09

Hello boys and girls. I have successfully installed asus xonar DX onto PCIE x16 slot on Linux 2.6.28-gentoo-r5 SMP on amd64 architecture. Version of alsa package - alsa-driver1.0.20, alsa firmware 1.0.19. I used alsa package and not kernel modules. Several channels seem to work fine(my speakers are broken, no back channels available, started holy war with creative about it, guess with fiasco with faulty speakers and xfi drivers i am supporter of creative no more, i am not gonna bad mouth them either just yet). So far so good. Microphone works, surround sound works too, I am pretty happy. Thanks for all people who advised me something. If i come across this problem - you will hear from me again ;) Specially
