[alsa-devel] Sampling rate limited to 48 kHz
Hi,
I have Turtle Beach Catalina Card (Envy24HT-S, VT1616 + WM8728) which I belive is exactly the same as Mad Dog Entertainer 7.1 ( http://techreport.com/reviews/2004q1/maddog-entertainer/index.x?pg=2 )
Card is recognized as Chaintech AV-710 but works very well ( so far I tested analog out through WM8728 and digital out ).
My problem is : I can't set sampling rate higher than 48000 on SPDIF out.
I know this card can go higher because :
1. It can go higher under Windows (High Sample Rate 2-channel mode)
2. If I "flash" eeprom with M-Audio Revolution 7.1 settings card can sync with my external DAC up to 96 kHz (DAC limit) and I can play 96kHz .wav file. This is not the way to go for me (analog part and SPDIF-in is lost)
I found this :
ice1724.c:390:static int get_max_rate(struct snd_ice1712 *ice) ice1724.c-391-{ ice1724.c-392- if (ice->eeprom.data[ICE_EEP2_ACLINK] & VT1724_CFG_PRO_I2S) { ice1724.c-393- if ((ice->eeprom.data[ICE_EEP2_I2S] & 0x08) && !ice->vt1720) ice1724.c-394- return 192000; ice1724.c-395- else ice1724.c-396- return 96000; ice1724.c-397- } else ice1724.c-398- return 48000; ice1724.c-399-} ice1724.c-400-
Tried to play with it, but no luck - I'm not developer :-)
How can I help with making ice1724 driver even better ?
Thanks, Marek

Hi,
alsamixer - impossible to set "Multi Track Internal Clock" beyond 48000
Well, then it's because the EEPROM content is somehow strange. It doesn't indicate that it has I2S connection. I guess it's because the board has both ac97 and I2S codecs. It's an interesting case. We'd first need to figure out the connections of these codecs.
When you use amp.c as it is, how well does the card work? I guess you having some mixer elements like "Master", "PCM", etc. They come from ac97 (vt1616). The driver creates no mixer elements for WM8728 on the other hand.
So, the question is, when you change "Master" or "PCM", which output (front, surround, clfe, side) is affected?
Also, when you change the values in wm_inits[] in snd_vt1724_amp_init(), especially, the values for WM_ATTEN_L and WM_ATTEN_R to other values, say, 0x20 (-16dB), which outputs are affected?

Hi,
As on this photo http://support.turtlebeach.com/site/kb_ftp/586117719.asp from the left :
1. Front Out (Channels 1/2) :
Vol reg : Master, PCM
2. Rear Out (Channels 3/4) :
Works only with "Alternate Level to Surround Out" set to [on] Vol reg : Headphone, PCM
3. Center/Sub Out (Channels 5/6) :
Couldn't get sound at all.
4. Surround Out (Channels 7/8) :
Works only with "IEC958" _not_ set to "PCM Out"
Vol reg : PCM
Also, when you change the values in wm_inits[] in snd_vt1724_amp_init(), especially, the values for WM_ATTEN_L and WM_ATTEN_R to other values, say, 0x20 (-16dB), which outputs are affected?
Recompiled modules with WM_ATTEN_L and WM_ATTEN_R set to 0x0020. Played some music. Unloaded original modules (/etc/init.d/alsasound stop) Replaced /lib/modules/2.6.18.6/alsa-driver Loaded newly compiled modules (/etc/init.d/alsasound stop) Played some music. All channels sounded the same.

Doesn't it have "Surround" mixer controls?

Weird..

OK, could you show the content of "alsactl -f somefile store" in the working state? Also, you can compare files in /proc/asound/card0/codec97#0/* files between working and non-working states.
Also, when you change the values in wm_inits[] in snd_vt1724_amp_init(), especially, the values for WM_ATTEN_L and WM_ATTEN_R to other values, say, 0x20 (-16dB), which outputs are affected?

Then this implies that the all signales go through only AC97, not WM codec. In this case, the limitation to 48kHz is correct. But, maybe we can switch the signal route dynamically between AC-link and I2S by AC97_CFG register.
