I can't use 3.31 release, but 3.19 release works on the same platform

　　Hi All:

　　My Bluetooth earphone is Motorola HT820. 

　　

　　1. When I try to use bluez-utils 3.31 on my desktop (Ubuntu7.10), there are some issues: (but there is no such issue when I use 3.19 version on this same platform). Should I update some other package besides bluez-utils and bluez-libs?

　　"

　　halley@azhao2ubtg2:~$ aplay /home/halley/media/audio/Track27.wav 

　　ALSA lib pcm_bluetooth.c:1501:(audioservice_recv) Error receiving data from audio service: Success(0)

　　ALSA lib pcm_bluetooth.c:1517:(audioservice_expect) Bogus message BT_GETCAPABILITIES_REQ received while BT_GETCAPABILITIES_RSP was expected

　　aplay: main:545: audio open error: Invalid argument

　　"

　　

　　2. When I use bluez-utils 3.19 version, application calls snd_pcm_hw_params() sometimes will got return value "1". (The function description says it will be 0 for success and negative number for failure). The positive value makes me puzzled.

　　

　　    /* Apply parameters */

　　 err = snd_pcm_hw_params(m_pAlsaPCMHandle, hwparams);

　　 if (err < 0) 

　　    {

　　        HXLOGL1 ( HXLOG_ADEV, "snd_pcm_hw_params: %s", 

　　                  snd_strerror(err));

　　        m_wLastError = RA_AOE_NOTENABLED;

　　 }

　　

　　    /* read buffer & period sizes */

　　    snd_pcm_uframes_t buffer_size = 0;

　　    snd_pcm_uframes_t period_size = 0;

　　

　　    if (err == 0)

　　    {

 

3. Ubuntu hardy has included bluez-utils 3.26 version; but I found there are many XRun errors when I use helix engine.
