[Alsa-devel] how to cross compile the alsa util?
Hello alls: I cross compiled the alsa-lib-1.04 to arm platform. The 2.6.6 kernel including alsa driver is ok on our ARM board, so I want to test the driver. how to do it? I think maybe the first step is to crosscompile the alsa utils to play a wave audio file. CC=arm-linux-gcc ./configure --host=i686-linux --target=arm-linux make make install then compiled and installed the libasound.*/ asound.h to /usr/lib and /usr/include/sys. Then I try to cross compile the alsa-utils: CC=arm-linux-gcc ./configure --host=arm-linux --target=arm-linux checking for libasound headers version >= 0.9.0... not present. configure: error: Sufficiently new version of libasound not found. So how to make it and is there any simple method to test the alsa?

RE: [Alsa-devel] ATI IXP SPDIF
hi, i happened to have that ASUS mobo (P4R800-VM) which has an ATIIXP/AD1888 and both PCM and ac3 pass through works with SPDIF. but the board i am trying to get working has an ATIIXP/ALC655 and i had a look at the realtek site and they had some drivers (http://www.realtek.com.tw/downloads/dlac97-2.aspx?lineid=5&famid=12&series= 8&Software=True) which looks like they were based off alsa-1.0.4. just doing a quick diff i see that they added some SPDIF stuff amongst other things. after testing and some code diffing this is what i figured: alsa-1.0.4 broken atiixp-spdif broken alc655-spdif realtek-alsa-1.0.4 broken atiixp-spdif working alc655-spdif alsa-cvsworking atiixp-spdifbroken alc655-spdif i am going to try and hack together some combination of realtek-alsa-1.0.4 and alsa-cvs and see if what i figured is right or not. it would be great if one of the alsa developers can look into realtek-alsa-1.0.4 and merge those changes into alsa. cheers, alex > -Original Message- > From: Takashi Iwai [mailto:[EMAIL PROTECTED] > Sent: Tuesday, May 25, 2004 2:45 AM > To: Alex Song > Cc: '[EMAIL PROTECTED]' > Subject: Re: [Alsa-devel] ATI IXP SPDIF > > > At Mon, 24 May 2004 16:16:42 -0700, > Alex Song wrote: > > > > hi, > > > > i am trying to get SPDIF output working on ATI IXP/Realtek > ALC655 and i am > > using atiixp.c from cvs (version 1.9) and linux kernel > 2.6.5. i tried > > playing back wav files through aplay and ac3 files with > ac3play and i > > couldn't get any output from either SPDIF over AC97 or > SPDIF Direct. analog > > output is fine. from the cvs logs i gather that SPDIF on > ATI IXP should work > > for some cases at least, has anyone got it to work? if so with what > > files/hardware/settings etc? > > it works fine on my test machine. it's an ASUS mobo (forgot the > model). > > % ac3dec -C some-48k.ac3 > > or > > % aplay -Dplug:spdif foo.wav > > but the direct SPDIF mode doesn't work... > > -- > Takashi Iwai <[EMAIL PROTECTED]> ALSA Developer - > www.alsa-project.org > --- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...

Ed, here's a script for 1:1 routing (hdspmixer preset 1) #! /bin/bash for out_left in $(seq 0 2 16); do let out_right=$out_left+1 let in_left=$out_left+16 let in_right=$out_right+16 amixer cset numid=5 $in_left,$out_left,32768 amixer cset numid=5 $in_right,$out_right,32768 done; This script assumes the hdsp is the default card, if it's not, just add '-c X' (where X is your hdsp's alsa card number) between 'amixer' and 'cset'.

The driver must not acknowledge the settled period with the midlevel and application before the specified time. Of course, if you're running into a rounding problem, you can acknowledge more periods at one time. In other cases, it's not very practical to program hardware to use different period sizes, because you need more interrupts for processing.

You can open it in non-blocking mode and set it to blocking later, if you want that behavior when writing data. -- Måns Rullgård [EMAIL PROTECTED] --- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...

[Alsa-devel] [Alsa-dev]detecing if a device is already used by an other app
Hi there, I am currently using two computers which have a crappy intl8x0 audio chipset, and these chipset cannot be used by two different apps in the same time. For example, if an audio app is using the soundcard, trying to launch xmms ( with alsa output plugin) gives an error message which says something like "check that no other app is blocking the device". But if I launch alsaplayer (alsa output plugin) instead of xmms, the app doesn't complain: it 'just' blocks on the snd_pcm_open call. Basically, after having looked at the source, is seems like this difference is coming from the flag in snd_pcm_open: if SND_PCM_NONBLOCK is used, opening an already opened device failed, if SND_PCM_ASYNC is used, the app just blocks, until the other app releases the device. Is there a (simple) way to use the blocking call and detecting if the device is already opened ?
